Z.: Automatic Image Segmentation Based on Human Color Perceptions

by Yu Li-jie - I.J. Image, Graphics and Signal Processing , 2009
"... Abstract—In this paper we propose a color image segmentation algorithm based on perceptual color vision model. First, the original image is divide into image blocks which are not overlapped; then, the mean and variance of every image back was calculated in CIEL*a*b * color space, and the image block ..."

of the texture blocks need to calculate and the edge information are stored for regional growing. The fuzzy region growing algorithm and color-edge detection to obtain a final segmentation map. The experimental segmentation results hold favorable consistency in terms of human perception, and confirm

Bilateral Filtering for Gray and Color Images

by C. Tomasi , 1998
"... tomasi @ cs.stanford.edu Bilateral filtering smooths images while preserving edges, by means of a nonlinear combination of nearby image values. The method is noniterative, local, and sim-ple. It combines gray levels or colors based on both their geometric closeness and their photometric similariv, a ..."

to human perception. Also, in contrast with standardjltering, bilateral filtering produces no phantom colors along edges in color images, and reduces phantom colors where they appear in the original image. 1

Spatio-temporal energy models for the Perception of Motion

by Edward H. Adelson, James R. Bergen - J. OPT. SOC. AM. A , 1985
"... A motion sequence may be represented as a single pattern in x-y-t space; a velocity of motion corresponds to a three-dimensional orientation in this space. Motion sinformation can be extracted by a system that responds to the oriented spatiotemporal energy. We discuss a class of models for human mot ..."

Recognition-by-components: A theory of human image understanding

by Irving Biederman - Psychological Review , 1987
"... The perceptual recognition of objects is conceptualized to be a process in which the image of the input is segmented at regions of deep concavity into an arrangement of simple geometric components, such as blocks, cylinders, wedges, and cones. The fundamental assumption of the proposed theory, recog ..."

of these properties is generally invariant over viewing position and image quality and consequently allows robust object perception when the image is projected from a novel viewpoint or is degraded. RBC thus provides a principled account of the heretofore undecided relation between the classic principles

Learning to detect natural image boundaries using local brightness, color, and texture cues

by David R. Martin, Charless C. Fowlkes, Jitendra Malik - PAMI , 2004
"... The goal of this work is to accurately detect and localize boundaries in natural scenes using local image measurements. We formulate features that respond to characteristic changes in brightness, color, and texture associated with natural boundaries. In order to combine the information from these fe ..."

Pfinder: Real-time tracking of the human body

by Christopher Richard Wren, Ali Azarbayejani, Trevor Darrell, Alex Paul Pentland - IEEE TRANSACTIONS ON PATTERN ANALYSIS AND MACHINE INTELLIGENCE , 1997
"... Pfinder is a real-time system for tracking people and interpreting their behavior. It runs at 10Hz on a standard SGI Indy computer, and has performed reliably on thousands of people in many different physical locations. The system uses a multiclass statistical model of color and shape to obtain a 2D ..."

Affective Computing

by R. W. Picard , 1995
"... Recent neurological studies indicate that the role of emotion in human cognition is essential; emotions are not a luxury. Instead, emotions play a critical role in rational decision-making, in perception, in human interaction, and in human intelligence. These facts, combined with abilities computers ..."

Coloring the Animated World: Exploring Human Color Perception and Preference through the Animated Film

by Kaitlin L. Brunick, James E. Cutting
"... Animated films present a unique set of challenges and questions to scholars examining films from a cognitive perspective. When the confines of the real world don’t exist as they do in live action films, the filmmaker is confronted with creating the entire narrative space from scratch (Buchan, 2011; ..."

Scientific discoveries regarding the perception of color also influenced its use in art and animation, making color an ideal

The Plenoptic Function and the Elements of Early Vision

Electrophysiologists have described neurons in striate cortex that are selectively sensitive to certain visual properties; for reviews, see Hubel (1988) and DeValois and DeValois (1988). Psychophysicists have inferred the existence of channels that are tuned for certain visual properties ..."
