Due: Friday, April 19, 1996. Assignments are due at the beginning of class. Please put your full name, and the assignment number on the upper right of the assignment. Please complete the following exercises from your text: Gonzalez and Woods. 4.2, 4.3, 4.4, 4.6,

Additionally, please answer the following: In contrast enhancement pixels may be pro cessed individually, and pixels can also be modified indirectly through means of a color look up table (CLUT). Nearly all PC's and workstations with color now include CLUT hardware. The CLUT is a hardware hash table for intensities that can be displayed on an output device (monitor). Because the look up table has fewer entries than the frame buffer, typically, the lookup table may be updated more quickly than actually modifying all of the pixels. Briefly describe (1 or 2 paragraphs) a point processing operation, other than con trast enhancement which can be optimized by using the CLUT.
