121 Image similarity - PSNR and SSIM
126 this is the PSNR (aka **Peak signal-to-noise ratio**). The simplest definition of this starts out
132 Then the PSNR is expressed as:
134 \f[PSNR = 10 \cdot \log_{10} \left( \frac{MAX_I^2}{MSE} \right)\f]
138 an invalid divide by zero operation in the PSNR formula. In this case the PSNR is undefined and as
235 costly, so while the PSNR may work in a real time like environment (24 frame per second) this will
238 Therefore, the source code presented at the start of the tutorial will perform the PSNR measurement
239 for each frame, and the SSIM only for the frames where the PSNR falls below an input value. For
240 visualization purpose we show both images in an OpenCV window and print the PSNR and MSSIM values to
