PurposeCurrently, a common method of reconstructing mannequin is based on the body measurements or body features, which only preserve the body size lacking of the accurate body geometric shape information. However, the same human body measurement does not equal to the same body shape. This may result in an unfit garment for the target human body. The purpose of this paper is to propose a novel scanning-based pipeline to reconstruct the personalized mannequin, which preserves both body size and body shape information.Design/methodology/approachThe authors first capture the body of a subject via 3D scanning, and a statistical body model is fit to the scanned data. This results in a skinned articulated model of the subject. The scanned body is then adjusted to be pose-symmetric via linear blending skinning. The mannequin part is then extracted. Finally, a slice-based method is proposed to generate a shape-symmetric 3D mannequin.FindingsA personalized 3D mannequin can be reconstructed from the scanned body. Compared to conventional methods, the method can preserve both the size and shape of the original scanned body. The reconstructed mannequin can be imported directly into the apparel CAD software. The proposed method provides a step for digitizing the apparel manufacturing.Originality/valueCompared to the conventional methods, the main advantage of the authors’ system is that the authors can preserve both size and geometry of the original scanned body. The main contributions of this paper are as follows: decompose the process of the mannequin reconstruction into pose symmetry and shape symmetry; propose a novel scanning-based pipeline to reconstruct a 3D personalized mannequin; and present a slice-based method for the symmetrization of the 3D mesh.

Body Shape Analysis

Purpose The purpose of this paper is to use body shape analysis and develop a 3D virtual body formation and deformation model that can accurately express size and shape. Design/methodology/approach In this paper, 1,882 sets of direct measurement data of Korean women in their 20s (19–29 years) were analyzed. These data sets were sourced from the sixth and seventh “Size Korea” anthropometric survey data. Through body shape analysis, the authors classified them into seven body types and selected their representative bodies. A 2D image based on the height, breadth, depth and length was first formed, and the representative virtual body was modeled using the polygon technique. The authors calculated the grading ratios for each body type according to the clothing sizing system, and modified the virtual body size type by morphing technique. Findings In order to accurately evaluate the fit in a virtual fitting system, it is necessary to study the body size and shape of the target age; this makes it possible to form virtual body reflecting the size and shape. Originality/value In this paper, the authors propose a new 3D virtual body formation method that is more accurate in shape and size compared to the present system. Through this, it will be possible to grasp the accurate simulation state in the virtual fitting system, and thereby evaluate the accurate fit.

PurposeConsidering two-dimensional features in the body shape classification system cannot fully reflect the three-dimensional (3D) morphological characteristics of human body. The purpose of this paper is to propose a 3D feature based method to characterize and classify the upper body shape of women, and then obtained the corresponding garment block and improved the fitness of clothing.Design/methodology/approachIn this study, the [TC]23D scanner was used to obtain human data, and 15 layers of cross-sections of young females’ upper body were extracted. In total, 240 space vectors were obtained with the center of the bust cross-section as the original point. By using the principal component analysis and K-means clustering analysis, the body shape classification based on the space vectors length was realized. The garment block corresponding to three body types was obtained using the 3D scanning data and the cross-section convex hull, and compared with existing garment block and evaluated fitness of the blocks.FindingsIn total, 11 main components used to characterize the 3D morphological features of young women were obtained, which could explain 95.28 percent features of young women’s upper body. By cluster analysis, the body shape of women was divided into three categories. The block of three body types was obtained by the construction of the convex hull model.Originality/valueThis paper investigates a classification method of the body shape based on space vector length, which can effectively reflect the difference of surface shape of human body and further improve the matching degree of human body and clothing.

To improve body-type classification research and personalized clothing, this study adopted a research method of “three-dimensional (3D) scanning + photos” for the body-shape classification of young females’ waist–abdomen–hip. A total of 178 female college students were recruited for manual, photo and 3D body measurement to get the main body information. Based on the data acquired from 3D scanning, the corresponding heights, angles and other parameters of the waist, abdomen and hip were selected and used to analyze the human body in two respects of shape and height. Then the body-shape indexes and the height indexes were respectively analyzed, and 16 shape characteristic indicators and four height characteristic parameters affecting the waist, abdomen and hip were extracted. Three types in shape and two types in height were obtained, and the main classification rules of the waist–abdomen–hip shape were also concluded to identify the body type based on the body measurements extracted from body photos, which realized the automatic body-type identification based on body photos. It was of great practical significance to provide a basis for personalized customization of fast clothing and the subdivision of the human body shape, which could meet the individual customer’s requirements.

Purpose – Detailed body sizes are prerequisite for made to measure or customized manufacture. Nowadays, detailed body sizes can be precisely obtained by using 3D scanners, however, the high prices of the scanners block the population for such approaches. The purpose of this paper is to provide an economical and accurate data-driven method which can predict detailed body sizes with a small number of feature sizes. Design/methodology/approach – First, the representative body sizes are extracted from dozens of detail body sizes by using factor analysis and garment knowledge. Among the representative body sizes, those that are easy to be measured are selected as the feature parameters (FPs). Second, by mining the database of the body sizes, mapping from the FPs to the detailed body sizes is expressed by a combination of radial basis function and multiply linear regression. Thus, for an individual human body, his/her detailed body sizes can be predicted by a small number of FPs. Findings – First, FPs which are easily measured and represent the main shape information of a human body are extracted. Second, detailed body sizes can be functionally predicted by the FPs. Originality/value – Traditionally, measuring dozens of body sizes for each human body is tiresome and the accuracy of the sizes depends on the experience of the gaugers. In this paper, a small number of body sizes are selected as the FPs which are easy to be measured and can functionally express the other body sizes. Thus, by only measuring the FPs, the detailed body sizes can be intelligently and automatically predicted. This approach is meaningful to improve the intelligence and accuracy of the measurement, so that even an inexperienced gauger is competent to obtain accurate detailed body sizes.

Purpose – The purpose of this paper is to develop a virtual body that resembles the customer’s body shape using only the minimum information provided by the customer and without requiring individually scanned data. Design/methodology/approach – The target of this study includes the three-dimensional scanned data of 91 senior women aged 60 or older and human body measurement data of 268 people. The parametric virtual body was generated in three steps: a basic virtual body, a trans-shaped virtual body, and a trans-sized virtual body. Findings – Using organic relationships found in the body shape factors of the lower body, this study developed an algorithm to generate elderly women’s parametric virtual lower body that is quick and reproducible. Having tested the reproducibility of the algorithm, the parametric virtual body showed excellent reproducibility vis-à-vis the personal scanned data in both the shape acceptability and size acceptability. Originality/value – Because virtual bodies in this study are based on the results of body shape analysis related to apparel design, those resembling customer body shapes can be quickly and accurately generated. In addition, because body shape information for target groups is provided to the clothing manufacturers, it will likely contribute significantly to enhancing clothes fitting.

ABSTRACTIf the human body is really a fabric, should surgeons be considered architects, as some surgeons describe themselves today? The author raises and analyzes this question, and he concludes that vsurgeons cannot be considered as such: the architect is the creator of his work —fabric or building—, but the surgeon is not the creator of this complex biological fabric —vulnerable and subject to deterioration and with an expiration date— which is the human body. This body is the object upon which his hands and instruments operate. The surgeon cures and heals wounds, immobilizes and aligns fractured bones in order to facilitate their good and timely repair, and cuts open the body’s surface in order to reach its internal organs. He also explores the body with his hands or instruments, destroys and reconstructs its ailing parts, substitutes vital organs taken from a donor’s foreign body, designs devices or prostheses, and replaces body parts, such as arteries and joints, that are damaged or worn out. In today’s culture, dominated by the desire to perfect the body, other surgeons keep retouching its aging façade, looking for an iconic and timeless beauty. This longing can drive, sometimes, to surgical madness. The surgeon is not capable of putting into motion, from scratch, a biological fabric such as the human body. Thus, he can’t create the subject of his work in the way that an architect can create a building. In contrast, the surgeon restores the body’s deteriorated or damaged parts and modifies the appearance of the body’s façade.RESUMEN¿Si el cuerpo humano fuera realmente una fábrica, podría el cirujano ser considerado su arquitecto, como algunos se pregonan en estos tiempos? Esta es la cuestión planteada por el autor y, a tenor de lo discurrido, su respuesta es negativa: porque así como el arquitecto es el artífice de su obra —fábrica o edificio— el cirujano no es el artífice de la complejísima fábrica biológica —vulnerable, deteriorable y caducable— que es el cuerpo humano, la cual le es dada como objeto de las acciones de sus manos y de sus instrumentos. El cirujano cura y restaña sus heridas, alinea e inmoviliza sus huesos fracturados para que su reparación llegue a buen término, penetra por sus orificios naturales o dibuja sobre la superficie corporal incisiones que le permitan llegar a sus entrañas, las explora con sus manos o mediante instrumentos, destruye y reconstruye sus partes enfermas, sustituye órganos vitales que no le ayudan a vivir por los extraídos de cuerpos donantes, y concibe, diseña y hace fabricar artefactos o prótesis, como recambio fragmentos corporales deteriorados o desgastados, como arterias o articulaciones. Otros cirujanos, en la predominante cultura de la modificación del cuerpo, retocan una y otra vez su fachada envejecida ineludiblemente por el paso del tiempo, empeñados en la búsqueda incesante de una belleza icónica y mediática e intemporal, una pretensión que puede conducir, y a veces conduce, al desvarío quirúrgico. En definitiva, el cirujano es incapaz de poner de pie, ex novo, una fábrica biológica como la del cuerpo humano y, por lo tanto, no puede ser su artífice, como lo es el arquitecto de su edificio. A lo sumo, es el restaurador de sus entrañas deterioradas y el modificador de su fachada, de su apariencia.

PurposeThe use of shoulder protectors is strongly recommended when carrying objects on the shoulder to ensure the health and safety of workers. Thus, this study aimed to develop and verify an ergonomic shoulder protector that considers human body shape and carrying posture from an ergonomic perspective. Ultimately, this study will present a shoulder protector with enhanced fit and safety for carrying workers at construction sites.Design/methodology/approachThe shoulder protector was designed and printed using three-dimensional printing technology with variable side neck points and shoulder point heights to reflect the human body's shoulder line shape and to position the carried object stably on the shoulder. The developed shoulder protectors were evaluated in terms of their fit according to the work posture of the carrier, adherence upon motion and durability through structural analysis.FindingsThe design of the shoulder protector for carrying workers followed the shoulder line. It is best placed above the side neck point by 1.0 cm and above the shoulder point by 2.0 cm. Its length is slightly shorter than the human shoulder for superior fit and safety.Originality/valueThe final shoulder protector (FSP) for carrying workers reflects the body curvature while enhancing fit and safety by considering activity and protective factors. As functional studies and evaluations on the need for protectors are scarce, this study provides fundamental data in the evaluation of protective gears.

Human body is the basement for people’s existence. All human consciousness seems to be resulted from their body. It is regarded as a subject that involved in all human activities and created thoughts as well as human values. Although through Nguyen Duy’s writing career, the poet didn’t intend to use body’s language as one of means of expression. However, the body marked a deep impression in his poetry showing the fundaments of his ideas and feelings of the subject. The language of the body in his poems tended to point out some important issues such as the origin of the body, the body in wars, and the body in poverty.

PurposeThe purpose of this study was to categorize the whole body shapes of overweight and obese females in the US and examine apparel fit based on the current ASTM sizing standards related to the body shapes categorized.Design/methodology/approachBody scan data from 2,672 subjects were used. To categorize their whole body shapes using 97 body measurements, principal component analysis with varimax rotation, a hierarchical cluster analysis and K-means cluster analysis were used. To compare the ASTM sizing standards for plus sizes (curvy and straight) and missy sizes (curvy and straight), five body parts (bust, under bust, waist, top hip, hip) using the formula for fit tolerance (measurement plus half of the interval) were compared with the ASTM sizing standards to determine the size appropriate for each body part.FindingsFive whole body shapes among overweight and obese females in the US were categorized: Rectangle-curvy; parallelogram-moderately curvy; parallelogram-hip tilt; inverted trapezoid-moderately curvy and inverted trapezoid-hip tilt. When the body measurements in each body shape were compared with the current ASTM sizing systems for both misses and plus sizes, four-fifths or more of overweight and obese female adults in the US would find it difficult to obtain a perfect fit for both tops and bottoms.Originality/valueIdentifying whole body shapes among overweight and obese women in the US contributes significantly, as it will help apparel companies that target the markets of larger women develop a new sizing system. This study is the first attempt to analyze fit by comparing the ASTM sizing charts with body measurements in each body shape group. Further, the study contributes to the body-related literature by filling gaps in missing whole BS categories among overweight and obese females.

The Subject

This chapter argues that the spatial description of being first emerged as historically dominant in the mythology and mythograms of prehistoric and Neolithic peoples, but at the same time was also inscribed on the body of the speaker of those same mythologies through speech. Therefore, the mythological description of being as space also presupposes a kinetic and historical transformation of the human body into a speaking body. The kinetic structure of this new surface of inscription is the subject of the present chapter. The thesis that follows is that the historical coemergence of spatial mythologies explored in the previous chapter and the new kinographic technology of speech follow the same dominantly centripetal field of motion during this time.
