SNR in Imaging

In imaging, Signal-to-Noise Ratio (SNR) describes the quality of an image by comparing the level of desired information (signal) to background fluctuations or random variations (noise). A high SNR means the image clearly shows the details you're interested in, with less interference from random disturbances, while a low SNR results in a grainy or blurry appearance. Enhancing SNR can involve techniques like increasing exposure, using better sensors, or processing images to reduce noise, all aimed at producing clearer, more accurate visuals.
