Recently, I learned about Android Image Processing in the system (I collected some information on the Internet and compiled my own testing program.) Here I will summarize: I. colormatrix class Colormatrix is a 5x4 matrix. The first line indicates

Previously, I learned about matrices in linear algebra and had some knowledge about the basic operations of matrices. I learned how to use matrices to change images when I used GDI + some time ago, after reading this article, I will summarize it

In the linear algebra before learning the matrix, there are some understanding of the basic operation of the Matrix, some time ago in the use of GDI + to learn how to use the matrix to change the image, after reading here to summarize the
