【摘要】 运用高斯滤波基本理论,通过对RGB图像进行分通道处理,即对R,G,B等3个通道分别进行高斯滤波处理,再经通道合并为彩色图像,并对经过处理后的彩色图像进行锐化处理。用本去网算法与扫描仪自带的去网算法进行了比较,在主观的基础上结合清晰度值,提出的去网算法所达到的效果更好。更多还原

【Abstract】 The basic theory of Gaussian filter was used in the process.RGB image was divided into three channels;R,G,and B channels were processed by Gaussian filter respectively;the processed image was combined to form color image;and the color image was processed through sharpening.The comparison was made based on the objective evaluation and combined with image definition value.The result showed that the discreening method is better than that of the scanner.更多还原
