这个是一个获取两个图像相似度的函数,对于图像处理和数字水印方面的编程者来说,会经常去计算两个图像的psnr值,从而来确定图像的相似度,使用matlab可以很方便的计算两个图像的psnr,但是由于matlab专业性很强,而且有没有版权保护,所以对于大批的使用VC语言的这方面的编程者,由于要经常使用而显得很麻烦。 通过调用get_psnr函数可以很方便的就得到两个图像的相似度。 -This is a similarity to obtain a function of two images for image processing and programming aspects of digital watermarking are concerned, will keep the two images to calculate the PSNR value, thereby to determine the similarity of images, the use of matlab can be easily the calculation of the two images psnr, but because matlab highly professional, and has no copyright protection, and therefore the use of a large number of VC language programming in this area, and due to frequent use, there appears to be very troublesome. Get_psnr by calling the function can be easily obtained from the two images on the similarity.
