Research of Color X-ray Medical Image Enhancement in HSV Space
Limei Liu · Journal of Yunnan Normal University · 2011
A color X-ray medical image enhancement algorithm in HSV color space has been developed.The medical image is transformed to HSV space first,then a sigmoid function is applied to the value and a line function is applied to saturation.Finally,we show enhanced image in RGB color space.Two parameters(a and b)were introduced in redefined Sigmoid function for the purpose of enhancing image adaptively.Another parameters(k1 and k2)were used in line function in order to increase common use.The experiment show that the proposed algorithm can work well to enhancing medical images.
