Going from unstructured cloud of points to surfaces is a challenging problem. However, as points are produced by a structure-and-motion pipeline, image-consistency is a powerful clue that comes to the rescue. In this paper we present a method for extracting planar patches from an unstructured cloud of points, based on the detection of image-consistent planar patches with J-linkage, a robust alg...

Image Understanding tesearch at CMU addresses a bmad spectrum of issues,from applications of machine vision to the development of new sensors and basic vision science. The Rapid site modeling-the generation of a detailed three-dimensional model of a surveyed site-is a critical problem for both military and civilian applications, including geographic database generation for cartography, reconnai...

Phase contrast X-ray tomography (PCT) enables the study of systems consisting of elements with similar atomic numbers. Processing datasets acquired using PCT is nontrivial because of the low-pass characteristics of the commonly used single-image phase retrieval algorithm. In this study, we introduce an image processing methodology that simultaneously utilizes both phase and attenuation componen...

The set üS can be identified with the set of all base point preserving maps of $ into itself. SO(n)> acting on S as R with a point a t infinity, is also a set of base point preserving maps of S onto itself. This defines SO(n) C.tiS. The induced map in homotopy is called the /-homomorphism. If we allow n to go to infinity we have the stable /-homomorphism. By Bott 's results [3] 7Ty(50)=Z, i = —...

We prove that the integral Hurewicz image of the cokernel J spectrum detects precisely the Kervaire invariant one elements and nothing else, which may be viewed as an analogue of the Curtis–Madsen conjecture on the unstable mod 2 Hurewicz image of Q0S.

The main key point of preferential image segmentation is to segment object of user interest based on intensities, boundaries and texture and ignoring the remaining portions. It utilizes a tree of shapes to represent the image content. This representation provides a hierarchical tree for the objects contained in the level sets of the image. The hierarchical structure is utilized to select the ca...

The security of digital images attracts much attention recently, and many different image encryption methods have been proposed. In 1999, J.-C. Yen and J.-I. Guo proposed a novel image encryption algorithm called BRIE (Bit Recirculation Image Encryption). This paper points out that BRIE is not secure enough from strict cryptographic viewpoint. It has been found that some defects exist in BRIE, ...
