![]() The impact of the successful mapping of the moon's surface map by the computer has been a huge success. on the thousands of lunar photos sent back by the Space Detector Ranger 7 in 1964, taking into account the position of the sun and the environment of the moon. They used image processing techniques such as geometric correction, gradation transformation, noise removal, etc. The first successful application was the American Jet Propulsion Laboratory (JPL). Common image processing include image enhancement, restoration, encoding, and compression. In image processing, the input is a low-quality image, and the output is an image with improved quality. It was aimed for human beings to improve the visual effect of people. The purpose of early image processing was to improve the quality of the image. Many of the techniques of digital image processing, or digital picture processing as it often was called, were developed in the 1960s, at Bell Laboratories, the Jet Propulsion Laboratory, Massachusetts Institute of Technology, University of Maryland, and a few other research facilities, with application to satellite imagery, wire-photo standards conversion, medical imaging, videophone, character recognition, and photograph enhancement. The generation and development of digital image processing are mainly affected by three factors: first, the development of computers second, the development of mathematics (especially the creation and improvement of discrete mathematics theory) third, the demand for a wide range of applications in environment, agriculture, military, industry and medical science has increased.įurther information: Digital image § History, and Digital imaging § History Since images are defined over two dimensions (perhaps more) digital image processing may be modeled in the form of multidimensional systems. It allows a much wider range of algorithms to be applied to the input data and can avoid problems such as the build-up of noise and distortion during processing. As a subcategory or field of digital signal processing, digital image processing has many advantages over analog image processing. For compression algorithms, see Image compression.ĭigital image processing is the use of a digital computer to process digital images through an algorithm. For artistic processing of images, see Image editing. This article is about mathematical processing of digital images.
