【摘要】 利用输入图像直方图和图像中已有的灰度级,结合互补色编码原理和人的视觉习惯,提出了一种基于直方图的色调、色饱和度和亮度空间(hue,saturation,intensity,HSI)伪彩色编码方法,用于对输入图像进行伪彩色变换.结果表明,该方法利用了原输入图像的有用信息,变换后得到的伪彩色更为丰富,具有较好的自适应性,且易于实现.可用于对实时性要求较高的军事、医学和卫星遥感等领域.更多还原

【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.更多还原
