WebLossless image compression. Images are all around us, from application icons to animated GIFs to photos. Image files can take up a lot of space, so computers employ a … WebTwo of the error metrics used to compare the various image compression techniques are the Mean Square Error (MSE) and the Peak Signal to Noise Ratio (PSNR). The MSE is the cumulative squared error between the compressed and the original image, whereas PSNR is a measure of the peak error. The mathematical formulae for the two are MSE =
