INTRODUCTION COMPUTER GRAPHICS IMAGE PROCESSING COMPUTER VISION >>>Graphics Timeline

Slide 3

COMPUTER GRAPHICS Computer illustrations is worried with all parts of delivering pictures utilizing a PC It worries with the pictorial combination of genuine or fanciful items from their PC based models BACK

Slide 4

IMAGE PROCESSING Image preparing is the opposite procedure of PC representation. Picture handling and Understanding regions focus on examination and remaking of 2D or 3D objects from their photos BACK

Slide 5

COMPUTER VISION Computer vision encourage more broadens exploration into comprehension pictures. It is the development of unequivocal, significant depictions of physical articles from pictures. BACK

Slide 6

GRAPHICS TIMELINE THEN The field submissively started 45 years prior with a couple lines on a cathode beam tube. Until mid 1980’s it was a little concentrated field because of lavish equipment and programming (application programs)

Slide 7

GRAPHICS TIMELINE Now We can create pictures practically vague from photos Interactive….highly intelligent!! In present times client controls the substance, structure and appearance of items by utilizing different information gadgets

Slide 8

GRAPHICS TIMELINE Now (proceeded with) Direct control is in overwhelming utilization We can make full length films completely by PC in general, the improvement of PC illustrations is driven both by the client\'s needs group and by the advances in equipment and programming

Slide 9

POPULARITY why is it so prominent - A photo is justified regardless of a 10000 words!!!!! It gives the most characteristic method for corresponding with a PC, since our observation capacities are preferable with pictures over with words It is one of the uncommon fields that has numerous business intrigues as there are examination intrigues (Thanks to Hollywood!!)

Slide 10

APPLICATIONS Computer representation is such a great amount popular as a result of its boundless mixture of utilizations Display Of Information Medium to pass on data Design Many applications exist in building and structural planning (CAD,VLSI) Simulation Graphical pilot training programs, diversions, plugs and instructive programming User Interfaces Visual ideal models in client association: windows, symbols, menus and so forth. Virtual Reality Applications

Wooden Mirror (D. Rozin, NYU) Sitting Movie Hand-still The wooden mirror has 830 bits of wood each around 40 mm square orchestrated into an octagon of 35 x 29 . Every bit of wood is associated with a servo engine that can tilt it around 30⺠here and there. The entire piece is lit from above with a couple spot lights, in a manner that when the pieces are tilted upwards they get to be brighter, and when they tilt downwards they get to be darker. The servo engines can position every piece in 255 positions hypothetically yielding 255 dark levels for each piece. In the focal point of the Mirror a small camcorder is covered.

Slide 12

Image Creation Camera is utilized to take a picture, put away on the film. Film records test of force that hits every point Intensity is shine of a point (measure of light reflected off the point), generally measured in lumens. Force is discretized to pixel values (persistent - > discrete)

Slide 13

Images.. CAMERA: Light beams come through lens in the camera and hits the film. Extent of light that hits the film is controlled by the opening (balanced in blend with the central length). Time length of time (to keep the entryway open for light to come-in) is controlled by shade speed. Us: Light from the outside world energizes nerves in our retina and mind comprehends the stereo pictures of our retina.

Slide 14

Discrete versus Nonstop universes Computers are in discrete world so we break the constant area (time and space) into discrete area. Activity: 24 to 30 outlines for each second Image: little dabs making up a lattice for the showcase. The little dabs are Gaussian, called pixels. Worth given to every pixel is called power.
