I have a loop and in the 240th step bgrPixel = frame.at<vec3b>(++rowCoord, ++colCoord); throws assert erroror at mat.hpp line 554

for (int rowCoord = 1; rowCoord <
> rowheight - 1; rowCoord++) for (int
> colCoord = 1; colCoord < colwidth - 1;
> colCoord++) { ///////////// //// /////
>                     frame.at<Vec3b>(Point(rowCoord,
> colCoord)) = black;

this is a common trap, it must be either:

frame.at<Vec3b>(Point(col, row))

or

frame.at<Vec3b>(row, col)
