基于定位算法的程序，和基于pca的程序，两者进行比较，有很好的处理效果，希望对你有用，-The pca based on the comparison of the particle swarm and pca algorithm, have very good processing effects, and hope to be useful to you, thanks a location based algorithm procedures, and based on the pca program, both carries on the comparison, have very good processing effects, and hope to be useful to you, thank you
