How to convert a YUV image to grayscale? I need to use it for image compression.
Show older comments
Initially I am given an RGB image but in image compression I need to convert this image to YUV format, which in MATLAB is easy. But is there any way to convert this YUV image to gray scale image so that DCT can be easily found? Or, is there any other way to find DCT for a YUG format image? Thank you.

If you have a YUV image, the gray scale version is the Y channel
grayImage = yuvImage(:, :, 1); % Channel 1, the Y channel, is the grayscale version
