Abstract

In this paper, a modified VLSI architecture for two-dimensional Radon Transform has been presented. The proposed architecture is primarily based on the analytical relationship between the pixels on horizontal and vertical raster scan line and also between the projection angles. The proposed architecture is compared against the existing ‘Parallel Pipeline Projection Engine’ (PPPE) architecture. Implementation of the proposed and PPPE architecture has been done on ‘Field Programmable Gate Array’ (FPGA). It has been observed that the modified architecture reduces the computational complexity, delay and latency as compared to PPPE.
二维Radon变换计算的改进PPPE结构
本文提出了一种改进的用于二维Radon变换的VLSI结构。该结构主要基于水平和垂直栅格扫描线上像素之间的分析关系以及投影角度之间的分析关系。将提出的体系结构与现有的“并行管道投影引擎”(PPPE)体系结构进行了比较。在“现场可编程门阵列”(FPGA)上实现了所提出的和PPPE架构。与PPPE相比,改进后的体系结构降低了计算复杂度、延迟和延迟。
