There are several techniques to obtain boundary of an object in a digital image. Some of the well known techniques are contour tracing and edge detection technique. The result of this boundary tracing is used for analyzing an object in the image. This result is critical for some certain image analysis. In this study, the techniques will be used for obtaining the fish boundary from a digital ima...

We analyze the quantum ground state structure of a specific model of itinerant, strongly interacting lattice fermions. The interactions are tuned to make the model supersymmetric. Due to this, quantum ground states are in one-to-one correspondence with cohomology classes of the so-called independence complex of the lattice. Our main result is a complete description of the cohomology, and thereb...

This paper presents an automatic registration system for aligning combined rangeintensity scan pairs. The overall approach is designed to handle several challenges including extensive structural changes, large viewpoint differences, repetitive structure, illumination differences, and flat regions. The technique is split into three stages: initialization, refinement, and verification. During ini...

We recorded responses in 107 cells in the primary visual area V1 and 113 cells in the extrastriate visual area V2 while presenting a kinetically defined edge or a luminance contrast edge. Cells meeting statistical criteria for responsiveness and orientation selectivity were classified as selective for the orientation of the kinetic edge if the preferred orientation for a kinetic boundary stimul...

In contrast to the body of work in more mesic habitats, few studies have examined boundary processes between natural and anthropogenic desert landscapes. Our research examined processes occurring at boundaries between a desert sand dune community and an encroaching suburban habitat. We measured responses to an anthropogenic boundary by species from multiple trophic levels, and incorporated meas...

In today’s technological world images plays a very important role. Images are very helpful in several fields like non-destructive testing. Medical diagnostics, surveillance and military etc. in image analysis and computer vision edge detection and boundary detection plays a very fundamental role. For image interpretation tasks and in image analysis processes the boundary of image will provide v...
