Digital image processing is a computer work that works on computers and can usually be used in industrial applications. Using image processing techniques and numerical image data, an improved or new image is obtained and object recognition can be performed. Image processing consists of several steps. The first step in this process begins with image capture, which, according to the reason, continues with the use of different techniques. These processes include mathematics and computer science and are used in fields such as design, manufacturing, security, medicine, electronics, machinery, architecture and geodesy. In this study; an evaluation was made by examining some studies made in different areas where image processing and image processing methods are applied.
