Abstract:

The basic concepts and methods of automatic palmprint recognition technology are described. In view of the requirements of the criminal investigation department, the importance of the palmprint minutia identification algorithm of high resolution is discussed. The matching method of minutia feature point is considered important. Matching algorithm is introduced by taking Cafis system as an example. The algorithm bottlenecks of palmprint feature point recognition are analyzed. These technologies have high speeds compared to the parallol technologies.

Key words: criminal investigation, palmprint identification, high resolution image, minutia feature point
