最长公共子序列的个人实验，输入两个不同的字符序列（要求必须是字母），将输出这两个字符序列的最长公共子序列。(Individual experiments longest common subsequence, enter two different sequences of characters (letters must be required), the output of the longest common subsequence of the two-character sequence.)

MATLAB计算机视觉与深度学习实战-运行视频(As a biological technology, face is difficult to be stolen and infection-free. In addition to that, it enjoys the authentication concealment and is never forgotten. Therefore, authentication based on face recognition will become the mainstream of future development. It has important and extensive application in various fields, and is also a hot topic at present biological characteristics identification technology research. Under the non-restrictive condition, the face recognition rate is not high, and its accuracy needs to be further improved. In this paper, the following aspects is analyzed)
