Parallel Hough Transform-Based Straight Line Detection and Its FPGA Implementation in Embedded Vision
Hough Transform has been widely used for straight line detection in low-definition and still images, but it suffers from execution time and resource requirements. Field Programmable Gate Arrays (FPGA) provide a competitive alternative for hardware acceleration to reap tremendous computing performance. In this paper, we propose a novel parallel Hough Transform (PHT) and FPGA architecture-associa...
متن کاملHough transform algorithm for FPGA implementation
In this paper a novel algorithm for computing the Hough Transform (HT) is introduced. The basic idea consists in using a combination of an incremental method with the usual HT expression to join circuit performances and accuracy requirements. The algorithm is primarily developed to fit Field Programmable Gate Arrays (FPGA) implementation that have become a competitive alternative for high perfo...
متن کاملImplementation of a Parallel Hough Transform Processor
Systolic arrays belong to the class of pipelined array architectures where many identical processing elements (PE ́s) are interconnected locally so that data can be passed from all PE ́s to their respective neighbors synchronously and in parallel. In principle, all of them perform the same basic operation on their current operands in one clock cycle. At the University of Mannheim a systolic proce...
متن کاملHough Transform Implementation by using Parallel Paradigms
Many problems in the field of computer simulation of systems in science and engineering present potential for parallel implementations through one of the three major paradigms of processor farming, geometric parallelism, and algorithmic parallelism. Processor scheduling determines which processes are assigned to specific processors and when. Static process scheduling techniques are successfully...
متن کاملFace Detection Using Scan-Line Based Hough Transform and MLP
A face boundary can be approximated by an ellipse with five-dimensional parameters. This property allows an ellipse detection algorithm to be adapted to detecting faces. However, the construction of a huge five-dimensional parameter space for a Hough transform is quite unpractical. Accordingly, we propose a scan-line-based Hough transform (SLHT) method for detecting faces from a symmetric conto...
