Description
Signal-to-Noise Ratio (SNR) is widely used for objective measurement of image quality due to its simplicity and convenience. SNR of a color image is often calculated as an arithmetic mean of SNRs for each color component. However, if SNR is expressed using logarithmic scale, the SNR derived by this method does not coincide with the SNR obtained by arithmetic mean of power of signal error of each color component. In this paper, we analyze difference of these SNRs and point out how SNR should be calculated for multi-component images.
