詳解

Matrix elements are stored row by row. Element (i, j) (i - 0-based row index, j - 0-based column index) of a matrix can be retrieved or modified using CV_MAT_ELEM macro:

uchar pixval = CV_MAT_ELEM(grayimg, uchar, i, j)
CV_MAT_ELEM(cameraMatrix, float, 0, 2) = image.width*0.5f;

To access multiple-channel matrices, you can use CV_MAT_ELEM(matrix, type, i, j*nchannels + channel_idx).

非推奨:

CvMat is now obsolete; consider using Mat instead.
