Nowadays, image processing, and digital image processing at that is among rapidly growing technologies. Digital imaging or digital image acquisition is the creation of a representation of the visual characteristics of an object, such as a physical scene or the interior structure of an object. Almost in every field, digital image processing puts a live effect on things and is growing with time to time and with new technologies. Many of the techniques of digital image processing, or digital picture processing as it was often called, were developed in the 1960s at the Jet Propulsion Laboratory, MIT, Bell Labs, University of Maryland, and a few other places, with application to satellite imagery, wirephoto standards conversion, medical imaging, videophone, character recognition, and photo enhancement. The book Web site, established during the launch of the second edition, has,. 1. Digital image processing by Rafael C. Gonzalez, Richard E. Woods, 2nd Edition Binary images Binary images are the simplest type of images and can take on two - images were coded, sent by telegraph, printed by a special telegraph printer. History of Digital Image Processing Early 1920s: One of the first applications of digital imaging was in the news-paper industry – The Bartlane cable picture Image Processing (2002) transmission service – Images were transferred by submarine cable between London and New York – Pictures were coded for cable transfer and It is a type of signal dispensation in which input is image, like video frame or photograph and output may be image or characteristics associated with that image. We can also say that it is a use of computer algorithms, in order to get enhanced image either to extract some useful information. Digital Image Processing Techniques is a state-of-the-art review of digital image processing techniques, with emphasis on the processing approaches and their associated algorithms. In this paper we, have presented a systematic study on image processing and its importance to the field of computer vision. There are two types of methods used for image processing namely, analogue and digital image processing. Analog Image Processing vs. Digital Image Processing. Keywords: Image, Digital Image, Compression, Enhancement, OCR, ATR. Image processing is a method to convert an image into digital form and perform some operations on it, in order to get an enhanced image or to extract some useful information from it. Image processing mainly include the following steps: 1.Importing the image via image acquisition tools; #Now You Get PDF BOOK : Digital Image Processing An Algorithmic Introduction Using Java. Where appropriate, complex processing procedures were summarized in the form of step-by-step algorithm formats.The references at the end of all chap-ters were updated also.
