DTW
DTW算法的程序,申请两个n*m的矩阵D、d,分别为累积距离和帧匹配距离。这里n和m为测试模版与参考模版的帧数。然后通过一个循环计算两个模版的帧匹配距离d。接下来进行动态规划,为每个格点 (i,j)都计算其三个可能的前续格点的累积距离D1,D2,D3。考虑到边界问题,有些前续格点可能不存在,因此加入一些判断条件最后利用最小值函数min(),找到三个前续格点的累积 距离作为累积距离,与当前帧的匹配距离d(i,j)相加,作为当前格点的累积距离。该计算过程一直达到格点(n,m),并将D(n,m)输出,作为模版匹配的结果。(DTW algorithm procedures, apply two n* m matrix D, d, respectively, accumulated distance and frame matching distance. Where n and m is a reference test pattern and the template frames. Then through a loop to calculate two frames template matching distance d. Next, dynamic programming, for each grid point (i, j) are calculated from the cumulative D1 before the renewal of its three possible lattice point, D2, D3. Taking into account the boundary problem, some former continued grid point may not exist, so add some conditions to determine the final use of the minimum function min (), found three former continued accumulation of grid points cumulative distance as the distance from the current frame to match the d (i, j) added, and a current cumulative distance grid. This calculation has reached the grid (n, m), and D (n, m) output, as a result of template matching.)

BlowfishEncryption
Blowfish Algorithm is a Feistel Network, iterating a simple encryption function 16
times. The block size is 64 bits, and the key can be any length up to 448 bits. Although
there is a complex initialization phase required before any encryption can take place, the
actual encryption of data is very efficient on large microprocessors.
Blowfish is a variable-length key block cipher. It is suitable for applications where the
key does not change often, like a communications link or an automatic file encryptor. It is
significantly faster than most encryption algorithms when implemented on 32-bit
microprocessors with large data caches.
