Automatic Extraction of Color Features from Landscape Images Based on Image Processing

The dominant color features determine the presentation effect and visual experience of landscapes. The existing studies rarely quantify the application effect of landscape colors through image colorization. Besides, it is unreasonable to analyze landscape images with multiple standard colors with a single color space. To solve the problem, this paper proposes an automatic extraction method for color features from landscape images based on image processing. Firstly, a landscape lighting model was constructed based on color constancy theories, and the quality of landscape images was improved with color constant image enhancement technology. In this way, the low-level color features were extracted from the landscape image library. Next, support vector machine (SVM) and fuzzy c-means (FCM) were innovatively integrated to extract high-level color features from landscape images. The proposed method was proved effective through experiments.

Application of Virtual Reality and Artificial Intelligence Technology in Fitness Clubs

With the continuous development and progress of virtual reality technology in recent years, the application of virtual reality technology in all aspects of real life is no longer limited to the military field, medical, or film production fields, but it gradually appears in front of the public, into the lives of ordinary people. The human-computer interaction method in virtual reality and the presentation effect of the virtual scene are the two most important aspects of the virtual reality experience. How to provide a good human-computer interaction method for virtual reality applications and how to improve the final presentation effect of the virtual reality scene is also becoming an important research direction. This paper takes the virtual fitness club experience system as the application background, analyzes the function and performance requirements of the virtual reality experience system in the virtual reality environment, and proposes the use of Kinect as a video acquisition device to extract the user’s somatosensory operation actions through in-depth information to achieve somatosensory control. This article adopts a real human-computer interaction solution, uses Unity 3D game engine to build a virtual reality scene, defines shaders to improve the rendering effect of the scene, and uses Oculus Rift DK2 to complete an immersive 3D scene demonstration. This process greatly reduces resource consumption; it not only enables users to experience unprecedented immersion as users but also helps people create unprecedented scenes and experiences through virtual imagination. The virtual fitness club experience system probably reduces resource consumption by nearly 70%.

Report of the IVth Workshop of the Spanish National Network on Mycotoxins and Toxigenic Fungi and Their Decontamination Processes (MICOFOOD), Held in Pamplona, Spain, 29–31 May 2019

The present publication collects the communications presented in the IV Workshop of the Spanish National Network on Mycotoxins and Toxigenic Fungi and their Decontamination Processes (MICOFOOD), held in the School of Pharmacy and Nutrition of the Universidad de Navarra (Pamplona, Spain) from the 29 to the 31 May 2019. More than 70 professionals from academia, the industry and public services have participated. The scientific program included: five sessions: sponsors (presentation and services), toxigenic fungi, toxicology, analysis and control, and reduction and prevention strategies. In total, 18 oral communications and 24 posters were presented. It is worth mentioning the high participation and quality of the communications from PhD students. The invited conference, entitled: “Mycotoxins within the framework of exposure assessment: past present and future”, was given by Dr. Barbara de Santis (Istituto Superiore di Sanità, Rome, Italy). The meeting ended with the roundtable: “From feed to fork: safe food without mycotoxins”, where representatives of feed and agrofood companies and public administrations discussed about the current situation and problems related with mycotoxins. Different prizes were awarded for the best oral presentation (Effect of Staphylococcus xylosus on the growth of toxigenic moulds in meat substrates, by E. Cebrian et al., University of Extremadura), and the best posters (Combined toxicity of aflatoxins and ochratoxin A: A systematic review by M. Alonso-Jaúregui et al., Universidad de Navarra; and Application of natamycin in products affected by toxigenic fungi by Torrijos et al., Universitat de València). The participants had the opportunity to learn about the history and gastronomy of Pamplona. Situated in the north of Spain, Pamplona is a city of Roman origin featuring a large gothic cathedral complex and a Vauban citadel of the 16th century.

Multimedia Teaching Platform Construction for Fashion Design Based on Simulation and Synchronous Teaching System

SOA technology can connect different service functions of application program through the well-defined interface and then form a sound distributed system through proper control process. SOA-based simulation and synchronous teaching system can give play to agility and high efficiency of this technology, so its practical value is high. Fashion design and other design majors have high requirements for multimedia software. The good presentation effect has great significance for design major teaching. Based on analyzing current situation of computer aided technology and fashion design teaching, theory construction of SOA-based simulation and synchronous teaching system was first conducted in this paper. Then, multimedia platform for simulation and synchronous teaching system was designed according to the specific requirements of fashion design teaching. Finally, the platform effect was tested. This paper verified that, SOA-based simulation and synchronous teaching system has good application effect in Fashion Design course and college teaching of design major.

Design and realization of relic augmented reality system of integration positioning and posture sensing technology

On the purpose of presenting the old appearance of the relics through digitalization, and overlapping the virtual scenes with the actual scenes at the relic site, in this paper, we introduced the positioning technology, posture sensing technology and system development technology, put forward constructing cultural relic tourism platform based on integration positioning and posture sensing technology, we conducted detailed research and analysis on the users’ experienced process of cultural tourism, designed a relic augmented reality system of integration positioning and posture sensing technology. This augmented reality system mainly utilizes positioning technology to guide the users to the correct location of the relic on the corresponding map, and then overlaps the virtual object with the real relic, achieveing a 360-degree view of the overlapping effect, and the presentation effect of near-small, far-big. The system mainly employs Unity to develop the system and realize the above system on mobile terminal. It is no longer limited to a fixed point experience environment, and is suitable for outdoor natural scenes, it makes a breakthrough on the traditional overlapping of virtual scenes and real scenes, realizes the precise overlap of virtual 3D scenes with actual images, and enables the users to feel the vicissitudes of history along the movement of the mobile device in outdoor natural scenes, so as to inherit the history and culture, enrich the information and add some fun to the displayed scene, it has the advantages of bringing people more immersive feelings compared with the traditional virtual display platform.
