Active contours3 (snakes) are a sophisticated approach to contour extraction in image interpretation. They challenge the widely held view that low-level vision tasks such as edge detection are ’bottom-up’ processes; features are extracted from an image and higher level processes interpolate to find a suitable representation. The principal disadvantage with such an approach is its serial nature;...

In this paper, we present a parallel implementation of an image feature extraction task on Connection Machine CM-5. We show that, given a 2048 2048 grey level image as input, the extraction of image features, which includes edge detection, thinning, linking, and linear approximation, can be performed in less than 1.2 seconds on a partition of CM-5 having 512 processing nodes. A serial implement...

In this paper, we present a fast parallel implementation of linear feature extraction on IBM SP-2. We rst analyze the machine features and the problem characteristics to understand the overheads in parallel solutions to the problem. Based on these, we propose an asynchronous algorithm which enhances processor utilization and overlaps communication with computation by maintaining algorithmic thr...

1 How many events? A key observation about serial verb constructions (SVCs) is that they express a single, perhaps complex, event rather than a series of distinct events a single serial verb complex describes what is conceptualized as a single event: this is repeatedly reported to be a clear intuition of native speakers, and can be demonstrated through semantic analysis. It follows that a seria...

Abstract:   Objectives: Flexion contractures of the proximal interphalangeal joint are of the most common complication result from surgical procedures and traumatic events.  Orthotic interventions for treatment of contractures may include serial splinting, serial casting, dynamic and/ or static progressive orthoses, or a combination of these orthoses.  This study aimed to determine the effect ...
