Calculate PSNR Between Two Color Images

This program primarily computes the Peak Signal-to-Noise Ratio (PSNR) between two color images as a quantitative measure for assessing image processing outcomes. After execution, the calculated PSNR value is stored in the variable PSNR for easy access and documentation. The implementation typically involves converting RGB images to luminance values or processing each color channel separately, followed by calculating the mean squared error (MSE) and deriving PSNR using the formula PSNR = 20*log10(MAX_I/sqrt(MSE)), where MAX_I represents the maximum possible pixel value. Additionally, the program can be extended to perform other image processing operations such as image enhancement and filtering, providing a comprehensive toolkit for image quality assessment. By utilizing this program, users can effectively evaluate the impact of various processing techniques and make informed adjustments to optimize results. Thus, this tool holds significant value for both research and practical applications in the field of image processing.
