学术论文 JPEG2000中小波变换的研究与FPGA实现
JPEG2000是新一代图像压缩标准,JPEG2000与传统JPEG最大的不同,在于它放弃了JPEG所采用的以离散余弦变换(Discrete Cosine Transform)为主的区块编码方式,而采用以小波转换(Wavelet Transform)为主的多解析编码方式.离散小波变换算法是现代谱分析工具,在图像处理与图像分析领域正得到越来越广泛的应用.由于JPEG2000标准具有复 ...
学术论文 基于FPGA的图像处理算法及压缩编码
本文以“机车车辆轮对动态检测装置”为研究背景，以改进提升装置性能为目标，研究在Altera公司的FPGA(Field Programmable Gate Array)芯片Cyclone上实现图像采集控制、图像处理算法、JPEG(Joint Photographic Expert Group)压缩编码标准的基本系统。本文使用硬件描述语言Verilog，以RedLogic的RVDK开发板作为硬件平台，在开 ...

Verilog HDL: Magnitude
For a vector (a,b), the magnitude representation is the following:
A common approach to implementing these arithmetic functions is to use the Coordinate Rotation Digital Computer (CORDIC) algorithm. The CORDIC algorithm calculates the trigonometric functions of sine, cosine ...
