Contrast Stretching

Contrast stretching is a technique used in image processing to enhance the visual quality of images. It works by expanding the range of brightness values in an image, making dark areas darker and bright areas brighter. This adjustment helps to improve details that may be hidden due to low contrast, making features more distinguishable. You can think of it as adjusting the knobs on your television to make the picture clearer and more vibrant, allowing for a better viewing experience. This method is commonly applied in photography, satellite imagery, and medical imaging to improve clarity and visibility.
