what is cv::setTo function
c++, opencv
Solution
`yy.setTo(0)` will set all the pixels to 0.
`yy.setTo(0, xx)` will set all the pixels who have a corresponding pixel with a non-zero value in the xx `Mat` to 0.
Example:
yy =
2 2 2
2 2 2
2 2 2
xx =
0 0 0
0 1 0
0 0 0
yy.setTo(0, xx) =>
yy =
2 2 2
2 0 2
2 2 2
Problem
I have a code written using OpenCV in C++, and this code uses a function setTo. Basically, it is used as: ``` cv::Mat xx; //prefedined and has some values cv::Mat yy; // initially empty yy.setTo(0,xx); ``` So can you explain what does this setTo means here? Does is put all zero values in yy, or it puts 1 where xx is non-zero and 0 where xx is zero too?
