get pixel value of an uint8 Mat

Question

In some other threads I read that a uint8 element can be accessed by

value = myMat.at<uint8_t>(Point(x,y));

My system doesn't recognize uint8_t as an datatype. Do I have to include something or do I have to use another datatype?

Answer 1

uint8_t is defined inside cstdint. So, you need to use #include <cstdint>
