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。
-The project name is: FPGA-based fingerprint identification module design.
The main contents are: the use of this module xilinx s Spartan 3E Series XC3S500E
FPGA-based control chip as the core, through the MFS300 Fujitsu fingerprint slide sensor capacitance extraction of the fingerprint image, and then extracted gray-scale fingerprint image filtering, image enhancement, binarization, denoising Second, refinement, etc. pre-treatment have been given clear fingerprint image, and then a clear fingerprint image from the extracted fingerprint feature points, into the external FLASH file as a template. Fingerprint matching using the same method to obtain a clear image of the fingerprint to establish than the template, and then will be the template file templates and the use of point pattern matching algorithm than the right, than the results obtained. The module is the realization of the use of soft-core embedded system management, the use of fingerprint recognition hardware implementation Platform: |

Description: 小波变换在信号处理、图像处理、模式识别、计算机视觉等
方面广泛应用。本文提出了一种基于Haar小波的时问序列相似
模式匹配模型．它首先对时间序列数据进行Haar小波变换．以
降低数据的维度。首先将所要查询的时间序列进行降维，也就是
对时间序列数据进行小波变换，对序列进行标准化131，得到降维
之后的小波序列．这样可以得到系数子集的良好近似采用尺度

判断相似性的距离函数．所以当在作完变换之后。通过低频分量
来压缩数据，成功的计算出实际距离的下界。如果计算的结果小
