  • How to optimize YUV to RGB color conversion code

    1er février 2016, par user_12

    I have written a function to convert an image in YUV420P to RGB but it is taking 30 millisecond to convert an image (size : 1280 x 720) into RGB, but when I am using ffmpeg function ( as this) to convert YUV image into RGB its taking only 2 millisecond for the same image. What is the problem with my code ? How can I optimize the code that I have written ??
    My code is given below

    int step = origImage->widthStep;
    uchar *data = (uchar *)origImage->imageData;
    int size = origImage->width * origImage->height;
    IplImage* img1 = cvCreateImage(cvGetSize(origImage), IPL_DEPTH_8U, 3);

       for (int i = 0; iheight; i++)
       {
         for (int j=0; jwidth; j++)
         {
           float Y = data[i*step + j];
           float U = data[ (int)(size + (i/2)*(step/2)  + j/2) ];
           float V = data[ (int)(size*1.25 + (i/2)*(step/2) + j/2)];

           float R = Y + 1.402 * (V - 128);
           float G = Y - 0.344 * (U - 128) - 0.714 * (V - 128);
           float B = Y + 1.772 * (U - 128);


           if (R < 0){ R = 0; } if (G < 0){ G = 0; } if (B < 0){ B = 0; }
           if (R > 255 ){ R = 255; } if (G > 255) { G = 255; } if (B > 255) { B = 255; }

           cvSet2D(img1, i, j,cvScalar(B,G,R));
         }
       }
