通过对木材图像进行3尺度的小波变换,在高频内判断图像的美化点,对确定的美化点进行美化处理,用蜂值信噪比、均方误差值和灰度曲线对美化效果进行评价。研究结果表明,该方法不仅美化了木材图像,也保留了木材纹理信息,同时用灰度曲线可以直观地分析图像的美化效果。
The article firstly treated the wood image using the three- scale wavelet transform,and then judged the beautification points in the high frequency image,and finally using the method treated the determined points,which was estimated by the PSNR,NMSE and the Profile curve.The results of the study showed that,this method not only beautifies the wood image,but also retained the wood texture information,and at the same time we can directly analysis the image beautification effect by using profile curve.
