Fingerprint_Identify
- 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
3_3_mean_diltter(ALU)
- 3*3均值滤波的VHDL语言实现的工程，对红外图像进行有效的去噪处理。这是其中的ALU模块，专门用来测试其延迟状况的模块。-3* 3 mean filter VHDL language works effectively on the infrared image denoising. This is one of the ALU module, designed to test the status of the module delay.
