What is Grayscale Image?
Grayscale is an image where the only colors are shades of gray. Grayscale images are usually composed of varying intensities of black and white, with no other colors present, in digital photography and imaging. As we know In contrast to the full-color images, which have a wide range of colors, this is not so. For simplicity, artistic effect, or reduction of file size, grayscale images are usually used.
Different techniques for analyzing, enhancing, or manipulating pixel intensity are used in grayscale image operations. Thresholding, where pixels are divided according to intensity thresholds for differentiating foreground and background regions, filtering techniques such as blurring or sharpening of the image to enhance its visual characteristics or reduce noise, and histogram equalization so that redistributing intensities give better contrast.
Some techniques used to improve contrast are the use of morphological techniques such as erosion or dilation to manipulate shape, skeletonization to reduce objects to their most basic structure, feature extraction to identify edges, corners or textures, and segmentation techniques to divide the image into meaningful regions.
Differentiate Between Grayscale and RGB Images
There are two primary digital picture formats that are used for distinct purposes: grayscale and RGB (red, green, or blue). Images in grayscale consist of black and white pixels, each of which has a grey color intensity. However, RGB images can exhibit a wide variety of hues since they are made up of three color channels: red, green, and blue.
