YUV图像用的比较多,而且YUV图像的格式众多(YUV格式可以参考YUV pixel formats),如何用OpenCV的Mat类型来存储YUV图像也是经常遇到的问题. 对于YUV444图像来说,就很简单.YUV的三个分量的采样方法一致,因此YUV三个分量的大小一致,可以用Mat的三个channel分别表示YUV即可.假设src是OpenCV默认的BGR三通道图像,和YUV444的转换如下,图像大小不变. // If src is CV_8UC3, dest is CV_8UC3 cvtCol
convert Matlab matrix to OpenCV Mat. Support CV_32FC3 only currently. The Code int matlab2opencv(cv::Mat &img, const mxArray *&mat){ mwSize num_dims = mxGetNumberOfDimensions(mat); const mwSize *dims = mxGetDimensions(mat); //for (int i = 0; i <
