We provided a new method that tried to transform the whole image to featured space and facilitated identification and self - elimination of disturbance according to the hue and luminosity features of eyes of human being . we gave the definition and description of the transformed space . a wavelet - texture filter was designed to distill space - transform - based feature of the image itself was executed 根据人眼对颜色、亮度等不同的敏感性以及图像本身的性质,仿人眼变换域分析图像形成光学滤色镜效果,减少复杂背景颜色和相似形状的多重干扰,并以此定义和表征变换域特征空间,给出变换域小波纹理车牌特征,成功提取车牌字符区域; 2
