Description: 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. Platform: |

Description: PSNR is used to measure the difference between two images. It is defined as
PSNR = 20 * log10(b/rms)
where b is the largest possible value of the signal (typically 255 or 1),
and rms is the root mean square difference between two images. The PSNR is
given in decibel units (dB), which measure the ratio of the peak signal
and the difference between two images. An increase of 20 dB corresponds to
a ten-fold decrease in the rms difference between two images. Platform: |

Description: The Cross Bilateral filter can enhance the PSNR of multi focus images that is in image fuison. Bilateral filtering is a local, nonlinear and non- iterative technique which combines a classical low-pass filter with an edge stopping function that attenuates the filter kernel when the intensity difference between pixels is large. As both gray level similarities and geometric closeness of the neighboring pixels are considered, the weights of the filter depend not only on Mahalanobis distance but also on the distance in gray/color space. The advantage of the filter is that it smoothes the image while preserving edges using neighboring pixels. CBF considers both gray-level similarities and geometric closeness of neighboring pixels in image one to shape the filter kernel and filters the image two. Platform: |

Description: This function displays the PSNR (peak signal-to-noise ratio) between two images. The answer is in decibels (dB).
PSNR is very common in image processing. A sample use is in the comparison between an original image and a coded/decoded image. Typical quoted PSNR figures are in the range +25 to +35dB.
The syntax for this file is PSNR(A,B), where A and B are MATLAB Intensity Images, with matrix-elements in the interval [0,1]
The function can be adapted for images with 256 gray levels. Platform: |
