Image processing is a technique used to perform operations on digital images, such as photographs or scanned documents. It involves converting an image into numerical form and then applying mathematical algorithms to analyze and manipulate the image in various ways. This can include enhancement of contrast, color correction, edge detection, shape recognition, compression, and many other techniques that help improve the quality, accuracy, and efficiency of image analysis and manipulation. Image processing is widely used in fields such as computer vision, medical imaging, remote sensing, and digital photography to extract valuable information from images or to perform specific tasks on them.
