MATLAB algorithm programs can be utilized to calculate the signal-to-noise ratio (SNR) of noisy images. SNR serves as a crucial metric for evaluating image quality, providing insights into the relative strength of signal versus noise in an image. By computing SNR, we can assess the noise level present in images and implement appropriate measures to enhance image quality. MATLAB offers built-in functions and computational tools that facilitate efficient SNR calculation for digital images. Through customized algorithm development, we can accurately and rapidly determine the SNR of noise-affected images using approaches such as mean squared error calculation or peak signal-to-noise ratio (PSNR) computation. Key MATLAB functions like immse() for mean squared error and psnr() for peak signal-to-noise ratio can be incorporated into the implementation, along with proper image preprocessing steps including noise estimation and signal power calculation.
