Interpretation of Complex Images, Literature Survey
Author: R. H. KausePublisher:
ISBN:
Category : Psychophysiology
Languages : en
Pages : 202
Book Description
This report is a review of the literature that might aid in measuring or describing complex images as stimuli, in relating this variable to the psychophysics of target identification, and in further specifying variables that may be important determinants of target identifiability. The body of this report is in four sections: (1) abstracts of articles containing general perceptual material, especially theories of form recognition or target identification; (2) abstracts of articles concerned with the experimental manipulation of perceptual variables known to be important determiners of form recognition and target identification; (3) articles concerned with measuring, changing, or simulating image parameters in some specified manner; and (4) abstracts of articles on the special characteristics of various sensor systems that will affect the resulting images used by the operator.
Picture Processing and Psychopictorics
Author: B.S. LipkinPublisher: Elsevier
ISBN: 0323146856
Category : Technology & Engineering
Languages : en
Pages : 535
Book Description
Picture Processing and Psychopictorics explores the selected aspects of perception and picture processing involving variables that are relevant to psychopictoric research. This book is organized into four parts encompassing 18 chapters. The first three parts cover the three classes of psychophysical variables, namely, contrast and border, shape and geometry, and texture. These parts also deal with the factors that influence the detection of objects in complex images. The discussion then shifts to the role of these factors in perception, as well as the computer analysis and manipulation of images with respect to these factors. The fourth part describes the programming systems for online experimental design and image manipulation. This work will be of great value to psychologists concerned with determining how the human extracts information from visual stimuli and to computer scientist concerned with developing programs and equipment to extract similar information from images.
Perception Through Experience
Author: M.D. VernonPublisher: Routledge
ISBN: 1315471310
Category : Psychology
Languages : en
Pages : 439
Book Description
The term ‘visual perception’ covers a very wide range of psychological functions. This title, originally published in 1970, which provides a broad survey of this vast field of knowledge, would have proved a valuable general account for students taking degree courses in psychology at the time. Professor Vernon examines a large number of experiments carried out over the previous twenty years, their findings, the conclusions drawn from them, and – equally important – the still unanswered questions which some of them raised. As the title suggests, Professor Vernon considers that – while much knowledge of the simpler perceptual processes had been gained in laboratory experiments – perhaps too little investigation had been undertaken into the more complex processes which normally determine understanding of and response to environment: the processes of identification and classification that depend to a considerable extent on learning, memory, attention, reasoning and language. An extensive bibliography is provided.

Image Quality Enhancement
Author: Robert W. BrainardPublisher:
ISBN:
Category : Aerial photography
Languages : en
Pages : 404
Book Description
A technique for enhancing the quality of imagery was investigated. The technique consists of obtaining a video signal from a transparency and adding to this signal its first and/or second derivative(s). The efficacy of the technique was evaluated by comparing imagery produced by the video signal and its derivative(s) with imagery produced by the video signal alone. The imagery investigated consisted of standard test patterns and aerial photographs. The processed test patterns were quantitatively analyzed to determine the resolution, contrast and acutance of the imagery. The results indicate: (1) differentiation enhances image quality, as indicated by the resolution, contrast and acutance metrics, (2) greatest enhancement is produced by operations which include second-order differentiation, and (3) the least enhancement is produced by first-order differentiation. The aerial photographic imagery shows the same enhancing effects as those obtained with the test patterns. (Author).
Visual Detection, Identification, and Localization
Author: Bernard LymanPublisher:
ISBN:
Category : Visual perception
Languages : en
Pages : 138
Book Description
The literature survey was undertaken to explore information on the nature of and conditions for effective visual perception at low light levels. From the survey, 407 reports or studies were selected for inclusion in the annotated bibliography. With a few exceptions, the material falls within the areas of detection, identification, and localization. Many laboratory studies are included which could undergo appropriate modification for repetition in natural settings at low light levels. In each annotation the purpose and the results or conclusions of the study are stated; method and procedure are indicated only briefly. (Author).
