Psychological Features

The article surveys the data of experimental studies in which the corneal reflex was used in the analysis of the visual perception process. Visual perception largely depends on the physiological characteristics of the human visual system, both individual and general. Blinking performs a number of functions, one of which is protection, including protection from unpleasant or undesired information. Blinking is closely related to the processes of concentration and disinterest. Blinking while watching a video is synchronized in single person and in a group of people watching the same video fragment. Blinking synchronization depends on the video plot; background video does not cause synchronization. Blinking synchronization is not gender specified. A longer duration of blinking is associated with a significant increase of the intervals between blinks. Accounting for these features of visual perception will allow to coordinate the work with video in several ways. First of all, it is an analysis of the reaction by monitoring the blinks while watching the video. Such analysis should contain a detailed and comprehensive decoding including electrophysiological, psychological and psychophysiological tools. Thus, the analysis of visual perception by studying the corneal reflex components requires an interdisciplinary approach and should be targeted to getting the results usable both for further studies of psychological features and principles of human visual perception and for further creation of most effectively perceived video.

The Impact

Visual attention is one of the most important mechanisms deployed in the human visual system (HVS) to reduce the amount of information that our brain needs to process. An increasing amount of efforts has been dedicated to the study of visual attention, and this chapter proposes to clarify the advances achieved in computational modeling of visual attention. First the concepts of visual attention, including the links between visual salience and visual importance, are detailed. The main characteristics of the HVS involved in the process of visual perception are also explained. Next we focus on eye-tracking, because of its role in the evaluation of the performance of the models. A complete state of the art in computational modeling of visual attention is then presented. The research works that extend some visual attention models to 3D by taking into account of the impact of depth perception are finally explained and compared.

Mosaic Images

Stitching gaps and misalignments in mosaic images can severely degrade the human visual perception of mosaic effects. Image stitching plays a key role in eliminating these unpleasant defects. In this paper, an image-stitching method for mosaic images with invisible seams is proposed, according to the research on the human visual system (HVS). By quantifying the human visual attention of images and visual discrimination about luminance difference and fine dislocations, each pixel in the stitching region is given a priority value for tracing a stitching line. Coupled with the processing of an optimal stitching line locating method and the multi-band blending algorithm, the pixels of discontinuous items in mosaic images decrease significantly and the stitching line is almost invisible. This study provides a new insight into the image-stitching field, and the experiments show that the results of the proposed method are more consistent with the human visual system in creating high-quality image mosaics.

ABSTRACTAny material inherently comes with its physical and chemical properties. The material scientists and allied engineers work on these properties in order to unearth newer findings. The change in the properties of a material through various process directly affects its characteristics and behaviour. Significant research on material science and metallurgical engineering have been done based on physical properties of the substance. Out of many physical characteristics of materials, this paper focuses on optical properties based on human visual perception. The particular research aims at an interdisciplinary approach to investigate how visual perception plays an important role in design and analysis of materials. Two particular cases have been analysed for this purpose, one in the domain of micro structure analysis and the other relating to the external physical visual characteristics of a material. Through this analysis a generic process framework is evolved which could be applied in material research as a theoretical discourse. Additionally an expert opinion survey reinforces the establishment of the evolved process framework. It would help scientists and engineers adapt and relate to a process so far as designing of new materials or comparative assessment of materials are concerned based on human visual perception.

AbstractThe basic principles of a multichannel model of the visual system of a human that functions as an operator performing surveillance on images formed by optoelectronic devices are described. A technique for experimental studying the model of the human visual system is proposed. The results of experimental studies aimed refining the parameters of the model of the visual system are presented. A satisfactory agreement between the calculated and experimental results indicates that the refined model of the human visual system is adequate.

Comparison Of The Results

The subject of this research is such a means of harmonization of composition of the image in a plane as the contrast. The article assesses the possibility and factors of using contrast for increasing the attractiveness of the designed photographic image. The author reviews the examples of photo images with appropriate use of contrast; provides the research data on the perception[WU1]  of contrast by human visual system.; explores correlation between contrast and the conditions for a harmonious composition; as well as reviews the connection between the properties of compositional elements of photography and the components of visual perception, discovered by R. Barthes in his work “Camera Lucida”. The author carries out the analysis of photographic images; compares the empirical data on the study of perception of contrast by a human; applies the methods of induction and deduction in analyzing the acquitted results and comparing them with the characteristics of a harmonious composition. The author’s special contribution consists in comparison of the results of empirical research of perception of contrast by a human in the context of dependence of the sensitivity of human visual system on the size of observable alternating contrast lines and the size of the dominant in relation to the image field object of composition. It is proposed to use high contrasts of the elements of detail drawing for reaching harmonization of composition of the designed image elements.  [WU1]

The article is devoted to the phenomenon of holographic human perception in the analysis of the architectural environment. Includes aspects of perspective-tonal perception of visual factors of holographic scanning of the human visual system. Aimed at understanding and reproducing the features and nuances of vision, in the context of summary analysis and reproduction of the system of energy flows in the elements of visual perception. The holographic factor of perception of reality is based on the difference between the work of the right and left eye, with the peculiarity of the angular adjustment of vision to the object of observation. The horizon line or the height of the perception of volumes, as well as the position of the spaces of the architectural environment remain dominant.
