评价图像处理结果是图像处理非常重要的一环,因此我认为有必要弄清楚评价所采用的数学模型的公式来源。由于本人没有学习过数字图像处理和相关的课程,因此没有自己弄清楚该公式的来源,网络中的博客也大多只是对该公式的实现,对公式来源没有做理解性的说明(感觉应该是公式太简单,没有必要说明 QAQ)。但作为一个...
A novel way in applying image compression error measurement algorithm using Peak Signal-to Noise Ratio (PSNR) is implemented under MATLAB environment. In this new approach, the structural degradation due to damage change in component composition or the presence of foreign bodies appearing in an image...

The PSNR block computes the peak signal-to-noise ratio, in decibels, between two images. This ratio is used as a quality measurement between the original and a compressed image. The higher the PSNR, the better the quality of the compressed, or reconstructed image. ...
