Description: 小波变换是一种快速发展和比较流行的信号分析方法, 其在图像处理中有非常重要的应用, 包括图像压缩, 图像去噪, 图像融合, 图像分解, 图像增强等。小波分析是傅立叶分析思想方法的发展与延拓。除了连续小波
(CWT)、离散小波(DWT), 还有小波包avelet Packet)和多维小波。本文主要介绍小波变换的发展及其在图像处理、的应用-Wavelet transform is a fast-growing and more popular method of signal analysis, image processing in a very important applications, including image compression, image denoising, image fusion, image decomposition, image enhancement and so on. Wavelet analysis is a Fourier analysis method development and extension. Apart from the continuous wavelet (CWT), discrete wavelet (DWT), there are wavelet packet (Wavelet Packet) and multi-dimensional wavelet. This paper describes the development of wavelet transform and its application in image processing Platform: |

Description: 本项目名称是：基于FPGA的指纹识别模块设计。
主要内容为：本模块采用xilinx公司的Spartan 3E系列XC3S500E
型FPGA作为核心控制芯片，通过富士通公司的MFS300滑动式电容指纹传感器对指纹图象进行提取，然后对提取的指纹图像进行灰度滤波、图像增强、二值化、二值去噪、细化等预处理，得到清晰的指纹图象，再从清晰的指纹图象中提取指纹特征点，存入外部FLASH作为建档模板。指纹比对时，采用同样的方法获得清晰的指纹图像，建立比对模板，然后将比对模板与建档模板利用点模式匹配算法进行比对，得出比对结果。该模块利用嵌入式软核实现系统的管理，利用硬件实现指纹识别，保证了系统功能的完整性与识别的正确性。该识别模块可用于门禁、考勤、安检、保险箱柜等很多方面，也可和计算机等设备联机使用，满足各个方面的不同需求，因此它的设计具有很广泛的应用前景和市场价值。
