Image processing is process of modifying nature of an image in order to improve its visual information about human interpretations & autonomously machine detection. Digital image processing is subset of electronics realm in which a picture is converted to an array of small integers known as pixels that reflect a physical attribute such as particular circumstance & data in digital memory before being h&led by a computer equipment. two primary application areas for digital image processing techniques that have generated attention are enhancing pictorial information for human interpretation & processing image data for storage, transmission, & representation for autonomous machine perception. Edges define boundaries, & edge recognition is one of most difficult tasks in image processing.. As a result, it is a basic issue in image processing. This article looks at many stages of digital picture processing. This study may be exp&ed in future by applying similar methods to a variety of digital pictures.
