Abstract:
A new gray image pseudo-color coding approach is proposed. Based on image′s histogram of the gray image and human′s visual conventions, the approach encoded the gray image in hue, saturation, intensity (HSI) space as a pseudo-color image enhance the visual effect of the image. The performance of the approach is evaluated and the experiment results show the superiority including adaptation and more color details in comparison with the existing methods. Finally, this approach could be used in the situation of martial, medicine and engineering.
KeyWords:
histogram; HSI space; pseudo-color coding
