HMMD color space and method for quantizing color using HMMD space and color spreading
The new MPEG standard, MPEG-7 is discussed in Chapter 11.
That standard somewhat sidesteps the thorny
question of whose favorite color space to use in a standard
definition by including six color spaces. One of them is a new
variant on HSV space, called HMMD Color Space, that purports to
allow a simple color quantization, from 24-bit down to 8-bit
color, say, that is effectively equivalent to a complex vector
color quantization
(i.e., considering a more careful, but also more expensive
mapping of the colors in an image into the color LUT).
