Total variation denoising

Total variation denoising is a technique used to remove noise from images while preserving their important details. It works by smoothing out small, random variations (noise) but maintaining larger, meaningful edges and textures. The method minimizes the total amount of variation (differences) in the image, effectively reducing clutter without blurring important features. Think of it as ironing out tiny wrinkles in a fabric, smoothing uneven spots while keeping the overall pattern intact. This approach is widely used in image processing to enhance clarity and quality without losing key information.
