ABSTRACT:
This paper establishes an efficient color space for the
contrast enhancement of myocardial perfusion images. The effects of histogram
equalization and contrast limited adaptive histogram equalization are
investigated and the one which gives good enhancement results is extended to
the suitable color space. The color space which gives better results is chosen
experimentally. Uniqueness of this work is that contrast limited adaptive
histogram equalization technique is applied to the chrominance channels of the
cardiac nuclear image, leaving the luminance channel unaffected which results
in an enhanced image output in color space.
