PART C

Answer any two full questions, each carries 20 marks.
A triangle PQR whose coordinate given by P (100,150), Q(200,250),and
R(300,200) is to clipped against a rectangular window whose coordinates are
given by A(150,150),B(150,),C(200,200) and D(200,150). Apply Sutherland
Hodgeman polygon clipping algorithm to generate a new set of output vertices.
Draw the final clipped polygon
Explain histogram equalization and perform histogram equalization on
following 8x8 image. The gray level distribution of image is given below
Gray level: 0 1 2 3 4 5 6 7
No. Of pixel: 8 10 10 2 12 16 4 2

Let ABCD be the rectangular window with A(10,10) B(80,10) C(80,70) and
D(10,70). Find region code for the end points to clip the line PQ using Cohen-
Sutherland algorithm with P(0,30)and Q(60,90).
