+ // Remarks for YBR newbees :
+ // YBR_FULL works very much like RGB, i.e. three samples per pixel,
+ // just the color space is YCbCr instead of RGB. This is particularly useful
+ // for doppler ultrasound where most of the image is grayscale
+ // (i.e. only populates the Y components) and Cb and Cr are mostly zero,
+ // except for the few patches of color on the image. //
+ // On such images, RLE achieves a compression ratio that is much better
+ // than the compression ratio on an equivalent RGB image.
