Technology,Image Processing and Computer Graphics

image processing and computer graphics have been treated as two different areas.Knowledge in both areas has increased considerably and more complex problems can now be treated.Computer graphics is striving to achieve photorealistic computer-generated images of three-dimensional scenes,while image processing is trying to reconstruct one from an image actually taken with a camera.In this sense,image processing performs the inverse procedure to that of computer
graphics.In computer graphics we start with knowledge of the shape and features of an object and work upwards until we get a two-dimensional image.To handle image processing or computer graphics,we basically have to work from the same knowledge.

We need to know the interaction between illumination and objects, how a three-dimensional scene is projected onto an image plane, etc. There are still quite a few differences between an image processing and a graphics workstation. But we can envisage that, when the similarities and interrelations between computer graphics and image processing are better understood and the proper hardware is developed, we will see some kind of general-purpose workstation in the future which can handle
computer graphics as well as image processing tasks. The advent of multimedia, i. e., the integration of text, images, sound, and movies, will further accelerate the unification of computer graphics and image processing.
