Thinning is a frequently used method for extracting skeletons in discrete spaces. This paper presents an efficient parallel Ž thinning algorithm that directly extracts medial lines from elongated 3D… (More)

Thinning on binary images is an iterative layer by layer erosion until only the “skeletons” of the objects are left. This paper presents an efficient parallel thinning algorithm which produces either… (More)

Thinning of a binary object is an iterative layer by layer erosion to extract an approximation to its skeleton. In order to provide topology preservation, different thinning techniques have been… (More)

In this paper we examine the problem of reconstructing a discrete two-dimensional set from its two orthogonal projection (H, V ) when the set satisfies some convexity conditions. We show that the… (More)

The reconstruction of 8-connected but not 4-connectedhv-convex discrete sets from few projections is considered. An algorithm is given with worst case complexity of O(mnmin{m, n}) to reconstruct all… (More)

Skeleton is a frequently applied shape feature to represent the general form of an object. Thinning is an iterative object reduction technique for producing a reasonable approximation to the skeleton… (More)

We address problems of the general form: given a J-dimensional binary (0-or 1-valued) vector a, a system of E of linear equations which a satisfies and a domain 3 C ~J which contains a, when is a the… (More)

Discrete tomography concerns the reconstruction of functions with a finite number of values from few projections. For a number of important real-world problems, this tomography problem involves… (More)

In this work, lossless grayscale image compression methods are compared on a medical image database. The database contains 10 different types of images with bit rates varying from 8 to 16 bits per… (More)
