Image filtering involves modifying pixels within an image to change or improve the image. Common filters include blur, sharpen, artistic effects, and more. Blur filters soften images by smearing pixels together, and are useful for reducing sharpness. Sharpen filters restore detail lost during image capture by intensifying pixel edges to counteract blurriness. Image filtering is a tool that allows for creative control over an image's appearance and can both beautify images and add visual effects.
