(a) Differentiate between the following compression algorithm:
1. Shannon -Fano Algorithm and 2. Huffman Encoding
(b) A statistical encoding algorithm is being considered for the transmission of a large number of long text files over a public network. Part of the file content .is as follows:
DODOCOCORICO
Using the Shannon - Fano algorithm compute the following:
i) the average number of bits per codeword
ii) the entropy of the source
iii) the minimum number of bits required assuming fixed-length codeword
iv) the compression ratio based on this algorithm if we assume an ASCII of 8 bits representation
Characteristics of vector drawings: Vector drawings are generally pretty small files as they include only data about the Bezier curves which form the drawing. The EPS-file format
2D Clipping Algorithms Clipping is an operation that eliminates invisible objects from the view window. To understand clipping, recall that when we take a snapshot of a scene,

Implement displacement mapping and bump mapping on a sphere. The displacement can be whatever your choice. The bump map can be whatever your choice as well.
Understanding the Concept of hypertext and hypermedia: For know the principle of Hypertext and Hypermedia we will look at how the human memory works.
Image Processing 1. How is sampling done? Explain quantization in digital image processing? 2. Explain in brief: (1) Image Subtraction (ii) Image averaging. 3. Explain in
Scan Line Algorithm A scan line algorithm determines the overlap intervals of the polygon with each scan line to obtain interior points of the polygon for assigning those point
