摘要
为了提高色盲患者分辨色彩的能力,提出了基于图像几何变换映射的色盲矫正方法。首先根据图像中颜色面两侧的颜色比例对颜色空间各个平面进行相应的几何变换,进而划分不同的颜色映射区域,通过颜色变换,生成色盲患者较易分辨颜色的图像。实验表明,该方法可以改善色盲患者对原本难以区分的颜色的分辨能力,同时计算速度快,有望满足实时处理的需要,性能上优于已有的方法。
In order to improve the ability of color discrimination for dichromats,a color blindness rectification method is proposed based on geometric transformation mapping of images.According to the color ratio on both sides of the specific plane in the color space,each plane is divided into different mapping regions by geometric transformation.Then the colors of the image are transformed into the ones which dichromats can distinguish.Experimental results show that this method can improve the color discrimination ability for dichromats.Meanwhile,this method is fast so that it is appropriate for real-time applications.It has a better performance compared with previous methods.
