Image Processing: Calculating Peak Signal-to-Noise Ratio (PSNR) in MATLAB with validated working examples
Detailed Documentation
In the field of image processing, Peak Signal-to-Noise Ratio (PSNR) is commonly used as a critical metric for evaluating image quality by measuring the extent of image distortion. The MATLAB implementation involves calculating the mean squared error between the original and processed images, then applying the logarithmic PSNR formula using built-in functions like 'immse' for error calculation and 'psnr' for direct computation. Through practical MATLAB routines, we can develop and validate code implementations that effectively assess the performance of various image processing algorithms. By analyzing PSNR values and conducting verification tests, we gain comprehensive insights into the effectiveness and feasibility of different image enhancement techniques.
