Image processing refers to the manipulation of digital images using mathematical operations and algorithms. This technique can be used to alter or improve an image. Image processing techniques range from simple resizing and brightness adjustments to advanced computer vision applications like noise reduction, contrast enhancement, object recognition, and edge detection. Some of the places where image processing is used include computer vision, remote sensing, forecasting, feature extraction, face detection, and optical character recognition. This technique can be used for both aesthetic and scientific purposes. For example, it can improve the appearance of a photograph, analyze satellite data, or reconstruct worn-out documents. Sampling software can assist in this process.
