Signal-to-Noise Ratio SNR is a general measure of the ratio between the power of a desired signal and the power of the background noise present in the signal. Mathematically, SNR is defined as: Where the "Signal Power" is the power of the actual signal of interest, and the "Noise Powe...

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)。但作为一个从来没接触过数字图像处理的小白来说,理解性的说明还是有必要的。
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...
