a little knowledge of opencv

in my course Adveranced processing of Img, I have finished my lab1, grey level tranformation.

based on opencv3.1, visual studio 2015, I used my own code to access threshold transformation, gama transformation, logarithm transformation and complementary tranformation.

In opencv 3.0 , there is no need to use IplImage, the container Mat can fully take the place of it .

Here are several functions of container Mat:

imread(“name”,int 0or1) 0:grey level. 1: not grey

imshow(“name of window”, picture)

Mat.ptr(i), get the pointer of line i;
