Digital Imaging

Abstract : Seminar ppt digital image processing and digital imaging is to create digital images, usually a physical attack. The term is often assumed to refer to or include the processing, packaging, storage, printing and displaying such images. A digital image can be created directly from a camera or similar physical attack. Alternatively, you can purchase the second instrument analog image, such as photographs, photographic film or printed on paper with a scanner or similar device. Many technical images, such as acquired tomographic equipment, side-scan sonar, or radio telescopes, the treatment is very complex image data. This digitization of analog data in the real world is known for digitizing, and is one of the sampling (discretization) and quantization. Finally, a digital image can also be calculated from a geometric model or mathematical formula. In this case, the image synthesis is the more appropriate name, and is often referred to as representation. digital authentication image is a [citation needed] new problem for suppliers and producers of high-resolution digital images, such as health care organizations, agencies of law enforcement and insurance companies. There are emerging methods of forensic science to analyze a digital image and determine if it has changed.
