Convert Colormap from RGB to YCbCr. Load an indexed image into the workspace. The colormap is in RGB colorspace. [I,map] = imread("forest.tif"); Convert the colormap to YCbCr. newcmap = rgb2ycbcr(map); Display the grayscale image with the original map and with the new map. ...
The model imports a 480p RGB image, then the Frame to Pixels block converts it to a pixel stream. Inside the HDL Algorithm subsystem, the Color Space Converter and Chroma Resampler blocks convert the pixel stream to YCbCr 4:2:2 format. The waveform of the input and output pixel stream ...
There is no 1-to-1 conversion between YCbCr and RGB. Using the same range of values, there are colors in both color spaces that cannot be represented in the other. When you do a conversion in either direction, you need to clamp the values to the range. ...
