Digital uses mega pixels ... vs film resolution is based on the area u have to record the image
The output as a result of IMAGE PROCESSING is an image ie a transformed image(enhanced) but in case of COMPUTER VISION the output is usually a decsion
computer graphic is a branch of computer science thats deals with theory and technique of computer image synthesis computer vision is a field that include method for acquiring processing ,analysing and understanding image
difference between 2d and 3d what is 3d colour image medical processing
In imaging science, image processing is any form of signal processing for which the input is an image, such as a photograph or video frame; the output of image processing may be either an image or a set of characteristics or parameters related to the imageComputer graphics are graphics created using computers and, more generally, the representation and manipulation of image data by a computer with help from specialized software andhardware
There is always a confusion among the newbies about the difference between Image Processing and Computer Graphics. Unless specifically mentioned , Computer Graphics is all about Synthesizing a new image from Geometry , Lighting parameters , Materials and Textures . The Emphasis is on Digital Image Synthesis. Image Processing is the process of manipulating an image acquired through some device . The image too often will be acquired from photographs,scanners , medical equipments. The emphasis is on Analysis and Enhancement of the image. Computer Vision is an area where Image Analysis is used a lot. Raster Operations dominate in the case of image processing. In the case of Computer Graphics , you will mix vector and raster operations to generate the final image.
Image processing is the method of processing data in the form of an image. Image processing is not just the processing of image but also the processing of any data as an image. It provides security.
Image processing involves various operations on images. An image is a collection of pixels. Each pixel has its position and resolution.
Signal processing's goals include many things, most importantly: sampling, quantization, noise reduction, image enhancement, image understanding, speech recognition, and video compression.
Digital image is depending on the camera resolotion, where optical image depends on the quality of the film. Normally an optical image will be better then a digital image, unless you are using high end digital camera. I hope this helps, Icko www.rtgallery.com
Computer Graphics: Synthesize pictures from mathematical or geometrical models.Image Processing: analyze pictures to derive descriptions (often in mathematical or geometrical forms) of objects appeared in the pictures.
there is no difference. ;)
