![]() ![]() Std::memcpy(greyImgForArrCopy.data, greyArr, 11 * 11 * sizeof(uint8_t)) omitting previously show examples for brevityĬv::Mat greyImgForArrCopy = cv::Mat(11, 11, CV_8U) I then use the HighGUI library to display the Mat object populated with a gradient of intensities of grey pixels within a named window. ![]() In this example I specify the dimensions, in rows and columns, of the Mat object being constructed as well as the data type of CV_8U indicating a single channel 8 bit unsigned integer, also defined as a uchar in OpenCV. Constructing an OpenCV Mat Object from C++ Arrayīelow is an example of creating a Mat object from a standard C++ two dimensional (ie, nested) array of unsigned 8 bit integers representing grey scale color intensities from black (0) to white (255). ![]()
