Image processing is mainly to do what

Image processing (imageprocessing), using a computer to analyze the image to achieve the desired results of the technology. Also known as image processing. Image processing generally refers to digital image processing. A digital image is a large two-dimensional array obtained by photographing with industrial cameras, camcorders, scanners, and other equipment, the elements of which are called pixels and their values are called gray values. Image processing techniques generally include 3 parts: image compression, enhancement and restoration, matching, description and recognition. Looking at the Wikipedia explanation again image processing is the technique of analyzing, processing, and manipulating images to make them satisfy visual, psychological, or other requirements. Image processing is an application of signal processing to the field of images. Most current images are stored digitally, and thus image processing in many cases refers to digital image processing. In addition, processing methods based on optical theory still hold an important place. Image processing is a subcategory of signal processing and is additionally closely related to the fields of computer science and artificial intelligence. Many of the traditional methods and concepts of one-dimensional signal processing can still be directly applied to image processing, such as noise reduction and quantization. However, images belong to two-dimensional signals, which have their own special aspects compared to one-dimensional signals, and are processed in different ways and from different perspectives.
