| 摘 要： | 针对CCD摄像机或扫描仪产生图像存在颜色偏差和非均匀性使图像质量下降 ,通过多元线性回归分析方法同时对图像的非均匀性和彩色失真进行补偿 ,使输出图像信号均匀且其色度值与输入信号的色度值相匹配。依据算法进行了仿真试验 ,结果表明补偿后图像与原图像相比大体相近 ,且比非均匀性校正和彩色校正分步进行方法计算量小 ,节省时间

| Abstract: | The image generated by CCD camera or scanner is non-uniformity and color distortion, which make image quality poor The image is compensated at the same time by multiple linear regression analysis, which make output image uniformity and its color is match to the color of input image The simulation result indicates that image after compensation is similar to the original image and its calculated cost and time consuming is less than sequence compensation |
