Contrasting theories of visual attention have emphasized selection by spatial location, individual features, and whole objects. We used functional magnetic resonance imaging to ask whether and how attention to one feature of an object spreads to other features of the same object. Subjects viewed two spatially superimposed surfaces of random dots that were segregated by distinct color-motion con...

Color, texture and shape information have been the primitive image descriptors in content based image retrieval systems. This paper presents a novel framework for combining all the three i.e. color, texture and shape information, and achieve higher retrieval efficiency using image and its complement. The image and its complement are partitioned into non-overlapping tiles of equal size. The feat...

To improve the discrimination power of color indexing techniques we encode a minimal amount of spatial information in the index. We propose an approach that lies between uniformly tesselating the images with rectangular regions and relying on fully segmented images. For each image we define 5 partially overlapping, fuzzy regions. From each region in the image we extract the first three moments ...

We treat the baryon as a composite system made out of a " core " of three quarks (as in the standard quark model) surrounded by a " sea " (of gluons and q ¯ q-pairs) which is specified by its total quantum numbers like flavor, spin and color. Specifically, we assume the sea to be a flavor octet with spin 0 or 1 but no color. The general wavefunction for spin 1/2 baryons with such a sea componen...

Worldwide, law enforcement agencies are encountering a substantial increase in the number of illicit drug pills being circulated in our society. Identifying the source and manufacturer of these illicit drugs will help deter drug-related crimes. We have developed an automatic system, called Pill-ID to match drug pill images based on several features (i.e., imprint, color, and shape) of the table...

Content-based image retrieval refers to making use of low-level visual features for grouping images into semantically meaningful categories. In this project we aim to study the technique of content-based image retrieval. We shall test the discriminating power of various features to classify images as landscapes and cityscapes by implementing [1]. The features used are: color histograms, color c...

We use the assumption of electric-magnetic duality to express the heavy quark potential in QCD in terms of a Wilson Loop W eff (Γ) determined by the dynamics of a dual theory which is weakly coupled at long distances. The classical approximation gives the leading contribution to W eff (Γ) and yields a velocity dependent heavy quark potential which for large R becomes linear in R, and which for ...

Designing low cost and high speed authentication solution for digital images is always an attractive area of research in image processing. In past few years because of widespread use of internet and network technology, concept of information distribution has been become habit rather than exception in daily life. In same aspects challenges involved with distribution of authenticate information h...
