I just learned about matlab, my first exercise is to convert the color space of an image from RGB to XYZ and represent the color value of that image to the corresponding color space, (specifically, the XYZ color space. ) I have tried quite a lot, can you help me with the solution?
The pixel cloud will be shown in the color space below.
lotChromaticity("ColorSpace","uv","View",3,"BrightnessThreshold",0)
you can refer to ( https://ch.mathworks.com/help/images/ref/plotchromaticity.html#d123e231937 )
thanks U so much! ^^
