We present a new shape skeleton pruning algorithm based on contour approximation and the integer medial axis. The algorithm effectively removes unwanted branches, conserves the connectivity of the skeleton and respects the topological properties of the shape. The algorithm is robust to significant boundary noise and to rigid shape transformations, it is fast and easy to implement. High accuracy...

Enhancing the self-symmetry of a shape is of fundamental aesthetic virtue. In this paper, we are interested in recovering the aesthetics of intrinsic reflection symmetries, where an asymmetric shape is symmetrized while keeping its general pose and perceived dynamics. The key challenge to intrinsic symmetrization is that the input shape has only approximate reflection symmetries, possibly far f...

Contour and skeleton are two main stream representations for shape recognition in the literature. It has been shown that such two representations convey complementary information, however combining them in a nature way is nontrivial, as they are generally abstracted by different structures (closed string vs graph), respectively. This paper aims at addressing the shape recognition problem by com...

This paper presents the details of flux-ordered thinning algorithm, which we refer to as Hamilton-Jacobi Skeleton (HJS). It computes skeleton any binary 2D shape. is based on observation that points have low average outward flux gradient distance transform. The algorithm starts by computing function and approximating values for all pixels inside Then a procedure called homotopy preserving itera...

The embryologists found the realistic human organ models and animations of development necessary for their studies. The main idea of this paper is a methodology producing a realistic animation of development by combining the L-system growth model with a physical model. The skeleton of a digestive system is a line skeleton with a tree structure. Therefore, its growth in length can be simulated b...

Recently, methods to accurately capture the motion of people gained increasing interest for variety of applications including interaction, animation, orthopedics, and rehabilitation. Compared to markerless approaches, marker-based methods are typically more accurate and are more robust against occlusions [8]. Major challenges in this context are to associate the observed markers with skeleton s...

Spurious words usually have no counterpart in other languages, and are therefore a headache in machine translation. In this paper, we propose a novel framework, skeleton-enhanced translation, in which a conventional SMT decoder can boost itself by considering the skeleton of the source input and the translation of such skeleton. By the skeleton of a sentence it is meant the sentence with its sp...

Different skeleton based parallel programming systems have been developed in past years. The main goal of these programming environments is to provide programmers with handy, effective ways of writing parallel applications. In particular, skeleton based parallel programming environments automatically deal with most of the difficult, cumbersome programming problems that must be usually handled b...

Photoirradiation of vinylcyclopropenes in a Pyrex tube provides 1-isopropylidene-3,8a-diphenyl-1,8a-dihydroazulene derivatives in moderate to good yields within 4.5-14 h. A plausible mechanism has been discussed for the formation of these interesting products.
