1. State the resolution of Facsimile, Document Images and Photographic Images?
Facsimile – 100 to 200 dpi Document images – 300 dpi (dots/pixels per inch) Photographic images – 600 dpi
2. What is the compression technique used in Facsimile and Document Images?
Facsimile - CCITT Group3 Document Images - CCITT Group4
3. What are the applications of Photographic Images?
Photographic images are used in Imaging Systems that are used for identification such as Security Badges Fingerprint Cards Photo Identification Systems
4. What is Raster graphics?
Raster graphics are digital images created or captured (for example, by scanning in a photo) as a set of samples of a given space. A raster is a grid of x and y coordinates on a display space. (And for three-dimensional images, a z coordinate.) A raster image file identifies which of these coordinates to illuminate in monochrome or color values. The raster file is sometimes referred to as a bitmap because it contains information that is directly mapped to the display grid.A raster file is usually larger than a vector graphics image file. A raster file is usually difficult to modify without loss of information, although there are software tools that can convert a raster file into a vector file for refinement and changes. Examples of raster image file types are: BMP, TIFF, GIF, and JPEG files.
5. Define computer graphics animation?
Computer graphics animation is the use of computer graphics equipment where the graphics output presentation dynamically changes in real time. This is often also called real time animation.
6. What is key frame?
One of the shape photographs that a film or video is made of the shape of an object is known initially and for a small no of other frames called keyframe
7. What is pseudo animation?
Pseudo animation is creating a sequence of stills, photographing or video graphing each still as one frame, and then later playing back the frames at a faster speed.
8. What is the normal speed of a visual animation?
Visual animation requires a playback of at least 25 frames per second
9. What is an intuitive interface?
The intuitive interface is one, which simulates the way a person would perform a corresponding operation on real object rather than have menu command.
10. What is Sprite?
A Sprite is graphics shape in animation and games programs. Each sprite provided in the system has its own memory area similar to but smaller than pixel RAM.
11. What is computer graphics realism?
The creation of realistic picture in computer graphics is known as realism. It is important in fields such as simulation, design, entertainments, advertising,research, education, command, and control.
