Study On Vein Image Processing System Based On DSP

Biological recognition technology applies more and more widely as the social developing and technology improving. Vein recognition technology has taken more attention in recent years with its unique advantages.This thesis aims at the request of the research of how to identify with the vein information, the development of the vein identify technology is introduced. A design method of embedded system based on DSP is proposed.This thesis designs the system hardware according to TMS320VC5416 processor of TI. The system includes: CCD sensor, A/D converter, FPGA, Synchronous RAM and FLASH ROM. Based on the system, the vein image processing arithmetic is researched for the characteristic of hands vein image and the binarization, thin, feature extraction and feature matching of the vein image are done, the application program of vein image processing is designed.The system achieves vein image processing of hands as passing the tests and satisfies the system design requests.
