Color indexing

by Michael J. Swain, Dana H. Ballard - International Journal of Computer Vision , 1991
"... Computer vision is embracing a new research focus in which the aim is to develop visual skills for robots that allow them to interact with a dynamic, realistic environment. To achieve this aim, new kinds of vision algorithms need to be developed which run in real time and subserve the robot's g ..."

Progressive Color Visual Cryptography

by Duo Jin, Wei-qi Yan, Mohan S. Kankanhalli , 2005
"... Visual cryptography is a powerful technique which combines the notions of perfect ciphers and secret sharing in cryptography with that of raster graphics. A binary image can be divided into shares which can be stacked together to approximately recover the original image. Unfortunately, it has not ..."

which enables visual cryptography of color as well as grayscale images. With the use of halftoning and a novel microblock encoding scheme, the technique has a unique flexibility which allows a single encryption of a color image but allows three types of decryptions on the same ciphertext. The three

Color visual cryptography schemes

by F. Liu - IET Inf. Security , 2008
"... Abstract: Visual cryptography scheme (VCS) is a kind of secret-sharing scheme which allows the encryption of a secret image into n shares that are distributed to n participants. The beauty of such a scheme is that, the decryption of the secret image requires neither the knowledge of cryptography nor ..."

VisualSEEk: a fully automated content-based image query system

by John R. Smith, Shih-fu Chang , 1996
"... We describe a highly functional prototype system for searching by visual features in an image database. The VisualSEEk system is novel in that the user forms the queries by diagramming spatial arrangements of color regions. The system finds the images that contain the most similar arrangements of ..."

The Plenoptic Function and the Elements of Early Vision

by Edward H. Adelson, James R. Bergen - Computational Models of Visual Processing , 1991
"... experiment. 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 ..."

Surround-screen projection-based virtual reality: The design and implementation of the CAVE

by Carolina Cruz-neira, Daniel J. Sandin, Thomas A. Defanti , 1993
"... Abstract Several common systems satisfy some but not all of the VR This paper describes the CAVE (CAVE Automatic Virtual Environment) virtual reality/scientific visualization system in detail and demonstrates that projection technology applied to virtual-reality goals achieves a system that matches ..."

Nonparametric model for background subtraction

by Ahmed Elgammal, David Harwood, Larry Davis - in ECCV ’00 , 2000
"... Abstract. Background subtraction is a method typically used to seg-ment moving regions in image sequences taken from a static camera by comparing each new frame to a model of the scene background. We present a novel non-parametric background model and a background subtraction approach. The model can ..."

The implementation of the model runs in real-time for both gray level and color imagery. Evaluation shows that this approach

Color Visualization of 2D Segmentations

by Christoph Dalitz, Tobias Bolten, Oliver Christen
"... This paper deals with the problem of coloring a two-dimensional segmentation result in such a way that each segment has a different color with the constraint that adjacent segments have sufficiently distinct colors to be easily distinguishable by a human viewer. Our solution for this problem is base ..."
