With this document, is intended to show some manipulation of signal processing techniques regarding continue and discrete signals, odd and even components, and periodic discreet signal, showing the mathematical part and the source code in Matlab on which it’s possible to try it out.

By this code developed for matlab you can find out the eyes located in the image useful for red eye removal on an image

该算法是K-SVD算法的一种改进算法。该算法可以用于稀疏字典的学习中。与传统方法相比，能够有效的降低计算量，提高字典更新的速度。(The algorithm is an improved algorithm of K-SVD algorithm. The algorithm can be used to sparse dictionary learning. Compared with conventional methods, it is possible to effectively reduce the amount of computation, to improve the speed of dictionary update.)
