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.
