摘要
当前,多数医学图像属于灰度图像,其对人眼的视觉效果不如彩色图像。为了提高图像的分辨率,根据人眼的视觉特点,结合计算机数字图像颜色模式和图像格式,采用灰度级-彩色变换方法,及基于视觉感知统计特性的伪彩色映射法,实现了使灰度图像变为伪彩色图像的目的。实验结果表明了该图像增强方法的有效性。当图像中含有极其微弱的有用的局部对比度信息时,效果尤佳。
Presently, most of the medical and industrial images are gray-scale images.However, human vision is less sensitive to difference between gray-scale pixels than that between color ones.In order to improve the resolving power of the images, according to characteristics of human vision and the color mode and the format of computer digital image, the method of gray-scale-color transform and the method of pseudo color mapping based on the characteristics of vision apperceive statistic are used to come true the a...
