The purpose of this exercise is to help you understand the various parameters that affect the quality of a compressed image. Using JPEG as an example, you are required to write a program to control the quantization matrices used for compression. A brief discussion of the impact is included as part of the assignment.

Follow these steps:

image file name: flower.bmp

Write a Java class that converts the bitmap image to JPEG format.

Add a second viewable pane on your image viewer in TME 1. The original pane should display the original bitmap image, and the second pane should display the converted JPEG image.

TME2_Sample_Screen.JPG

Add a mechanism to input the quantization matrix. It should have three options: (a) default JPEG matrix - the numbers can be found on Table 9.1 and Table 9.2 of the textbook; (b) a constant number; (c) DC component only (i.e. set all other numbers to zero).

Add an option to the File menu to output the compressed JPEG image to the hard disk.
