Description: Histogram specification is a technique used in image enhancement that modifies the histogram of an image to match a specified histogram. This technique is fundamental in image processing, as the histogram represents the distribution of pixel intensity levels in an image. By adjusting the histogram, visual characteristics such as contrast and clarity can be improved. Histogram specification is based on the idea that by transforming the intensity levels of an original image to resemble those of a reference image, a more balanced and appealing visual representation can be achieved. This process involves creating a transformation function that maps the intensity values of the original image to those of the target image, allowing for precise adjustments in brightness and contrast. The technique is particularly useful in situations where images may be underexposed or overexposed, and there is a need to restore details that might otherwise be lost. In summary, histogram specification is a powerful tool in image enhancement, enabling users to achieve more satisfying and professional visual results.
