The automatic assessment of the aesthetic quality of a photo is a challenging and extensively studied problem. Most of the existing works focus on the aesthetic quality assessment of photos regardless of the depicted subject and mainly use features extracted from the entire image. It has been observed that the performance of generic content aesthetic assessment methods significantly decreases when it comes to images depicting faces. This paper introduces a method for evaluating the aesthetic quality of images with faces by encoding both the properties of the entire image and specific aspects of the face. Three different convolutional neural networks are exploited to encode information regarding perceptual quality, global image aesthetics, and facial attributes; then, a model is trained to combine these features to explicitly predict the aesthetics of images containing faces. Experimental results show that our approach outperforms existing methods for both binary, i.e., low/high, and continuous aesthetic score prediction on four different image databases in the state-of-the-art.

Several scholars have focused on the different approaches in designing convivial urban spaces, but literary evidence shows that the essence of aesthetic design in public urban spaces, by referring to the main dimensions involved in the shaping of urban vitality, has not been adequately researched. In this regard, this study, by hypothesizing that the quality of urban design leads to a vital urban environment, focuses on urban vitality from the aesthetic point of view. Thus, in using qualitative grounded theory as a main methodological tool and using a systematic review of the related literature as the main induction approach for collecting qualitative data, five main dimensions of urban vitality, which are necessary to attain a correlation with the aesthetic quality of urban design, were conceptualized. The study concludes that the aesthetic design of an urban setting has a direct effect on the active involvement of its users and that this, therefore, has a direct consequence on the level of public urban vitality, manifested. Integrating the complexity theory with the five main dimensions used for assessing urban vitality was suggested as a viable area for further research.


Existence of a heritage / historical structure is the one that adds meaning to urban or rural space. The perceptual quality of the structure enhances the aesthetic sense to the settings or place. The aesthetic sense makes the place, a visual appealing entity with augment of identity. It develops a sign and symbol to the place. Without that, the meaning is lost, identity is destroyed and placelessness is formed. Urbanization and globalization always concentrate more on development, without understanding the basic meaning and cultural heritage of any built environment with its tangible and intangible aspects. This paper explores the ideas and thought process of the architects, urban design theorists, and psychologist in considering perceptual qualities of a structure and it turns in relation with the feature of a Dravidian style Rajagopuram that acts as an entrance gate way to a heritage precinct .

Low-light image enhancement algorithms (LIEA) can light up images captured in dark or back-lighting conditions. However, LIEA may introduce various distortions such as structure damage, color shift, and noise into the enhanced images. Despite various LIEAs proposed in the literature, few efforts have been made to study the quality evaluation of low-light enhancement. In this article, we make one of the first attempts to investigate the quality assessment problem of low-light image enhancement. To facilitate the study of objective image quality assessment (IQA), we first build a large-scale low-light image enhancement quality (LIEQ) database. The LIEQ database includes 1,000 light-enhanced images, which are generated from 100 low-light images using 10 LIEAs. Rather than evaluating the quality of light-enhanced images directly, which is more difficult, we propose to use the multi-exposure fused (MEF) image and stack-based high dynamic range (HDR) image as a reference and evaluate the quality of low-light enhancement following a full-reference (FR) quality assessment routine. We observe that distortions introduced in low-light enhancement are significantly different from distortions considered in traditional image IQA databases that are well-studied, and the current state-of-the-art FR IQA models are also not suitable for evaluating their quality. Therefore, we propose a new FR low-light image enhancement quality assessment (LIEQA) index by evaluating the image quality from four aspects: luminance enhancement, color rendition, noise evaluation, and structure preserving, which have captured the most key aspects of low-light enhancement. Experimental results on the LIEQ database show that the proposed LIEQA index outperforms the state-of-the-art FR IQA models. LIEQA can act as an evaluator for various low-light enhancement algorithms and systems. To the best of our knowledge, this article is the first of its kind comprehensive low-light image enhancement quality assessment study.

The article presents selected methodological assumptions of developing and evaluating landscape attribute maps that could be used in the process of the implementation of the European Landscape Convention (ELC). The Convention led to the passing of the Act of 24th April 2015 on the modification of some acts due to the enhancement of landscape protection tools. Article 7 implements changes in the Act of 23rd March 2003 on spatial planning and land use management. Determining general rules for landscape auditing and defining the priority landscape are elements of the changes. On 11th September 2015, the regulations that partially carry out the recommendation of the Convention entered into force. The regulations oblige local governments to conduct landscape auditing (not less often than every 20 years). The article presents a new method for evaluating the aesthetic-scenic value of landscape (EEVL), developed by the author on the basis of conceptual works done between 2004 and 2008. Tests of this method started in 2008. Then an assessment of the aesthetic value of the municipality of Pozezdrze in the Masurian Lake District was made. The three measurements, collected in 2008, 2012 and 2016, were then used in comparing the dynamics of landscape transformations considering the aesthetic value over 8 years. The research enabled the assessment of the usefulness of the method in landscape auditing.

The paper describes the results of a research activity on the design of a positioning system which includes both a physical 3-DOF and virtual platforms which carries out a Desktop Haptic Interface (DHI). The positioning system allows the user to interact with a virtual shape through a combination of linear and rotation motions, some of them driven by the user and some driven by the virtual shape. On the other hand, by rendering a physical 2D cross-section through the DHI permits the assessment of virtual prototypes of industrial products with aesthetic value. Typically, virtual objects are modified several times before reaching the desired design, increasing the development time and, consequently, the final product cost. The desktop haptic system (which includes the positioning system and the DHI) that we propose here, will reduce the number of physical mockups during the design process allowing designers to perform several phases of the product design process continuously and without any interruption. In particular the system is developed with the aim of supporting designers during the evaluation of the aesthetic quality of a virtual product.

An important topic in evolutionary art is the development of systems that can mimic the aesthetics decisions made by human begins, e.g., fitness evaluations made by humans using interactive evolution in generative art. This paper focuses on the analysis of several datasets used for aesthetic prediction based on ratings from photography websites and psychological experiments. Since these datasets present problems, we proposed a new dataset that is a subset of DPChallenge.com. Subsequently, three different evaluation methods were considered, one derived from the ratings available at DPChallenge.com and two obtained under experimental conditions related to the aesthetics and quality of images. We observed different criteria in the DPChallenge.com ratings, which had more to do with the photographic quality than with the aesthetic value. Finally, we explored learning systems other than state-of-the-art ones, in order to predict these three values. The obtained results were similar to those using state-of-the-art procedures.

ABSTRACT The Effect of Telajakan-Front Yard Conversion into an Artshop Toward Human Comfort Index and Landscape Aesthetic in Tegallalang Village Telajakan, a Balinese typical home yard, has located in front, right or left, or in the back of the yard. The study only focused on telajakan front yard along the way of Tegallalang Village which is usually used as a garden or planted area, although many of them turning into an artshop. The purpose of the study was to determine the effect of telajakan conversion into an artshop using user’s comfort index and landscape aesthetic measurement. Methods used in this study was temperature humidity index (THI) with the data of temperature and humidity. In addition, to assessed the aesthetic quality of the landscape used scenic beauty estimation (SBE) method by taking a photo of each landscape element representing the land use. Result showed that user’s comport index was low (THI valued ranged from 24,47 to 27,39) and categorized as uncomfortable to the tropics area. Further, the aesthetic quality resulted that the lowest SBE quality was -80,21 and highest SBE quality was 138,42. The aesthetic quality of the majoring landscape along the way of Tegallalang valued as a low category (53,33%), medium category (28,88%), and high category (17,77%). As a results, the conversion of telajakan into an artshop caused low of user’s comfort index and low of aesthetic quality to the landscape.   Keywords: comfort index, landscape aesthetics, telajakan, temperature humidity index (THI), scenic beauty estimation (SBE).

AbstractLittle is known of how vertebrate pest and beneficial species respond to cover crops in vineyards and orchards. During spring 19941 interviewed 22 people who work with cover crops in California and searched for vertebrates and their signs in 36 field plots where cover crops were grown. Farmers usually relaxed concern for vertebrate pests after planting cover crops. But cover crops were thought to increase venebrate damage to trees and vines when planted continuously across the rows or grown in orchards and vineyards less than three years old. Vertebrates usually were not abundant or harmful to the commercial crops and cover crops I examined. Gophers were most abundant in older, uneven, scrappy, or weedy cover crops. They preferred beneficial and insectary blends and Cahaba white vetch, and were least abundant in grasses, subclover mixes, and bur medic. Voles preferred nontillage clover mixes, but avoided bare ground under vine and tree rows. All small mammals were more numerous near streams and recently tilled fields. Cover crops attracted many predatory vertebrates, which improve the aesthetic quality of the farm and might keep animal damage to economically acceptable levels. Cover crops can contribute to wildlife conservation in California, especially if the area in cover crops continues to increase.
