Description: Local contrast is a measure of the difference in luminance between a specific area of an image and its immediate surroundings. This concept is fundamental in image enhancement, as it allows for the highlighting of details that might go unnoticed in standard viewing. Through local contrast, subtle variations in lighting and color can be identified, resulting in more dynamic and visually appealing images. This type of contrast focuses on small areas, unlike global contrast, which considers the image as a whole. Manipulating local contrast can enhance the perception of textures and edges, making elements of the image stand out more effectively. In various applications such as photography, graphic design, and medical visualization, local contrast is crucial for achieving optimal results. By adjusting local contrast, artists and technicians can guide the viewer’s attention to specific areas, improving visual narrative and image clarity. In summary, local contrast is a powerful tool in image enhancement, allowing for precise control over how details and visual characteristics are perceived in an image.
