Image Filtering

Image filtering is a process used to modify or improve images by applying mathematical operations to each pixel or small groups of pixels. Think of it as a way to enhance details, remove noise, or emphasize certain features. For example, smoothing filters can make an image look softer by averaging nearby pixels, while sharpening filters can make edges more defined. Filters can also detect specific patterns or features within an image. Overall, image filtering helps prepare images for better analysis, viewing, or artistic effects by targeting certain visual characteristics through systematic adjustments.
