Digital Imagery: The Basic Idea

Digital Photography

Compressing the original digital image Original Matrix – this one describes the image Transpose of Transforming Matrix W Transforming Matrix W

Original picture A digitized version 64 total pieces of data to describe this picture– Takes a lot of space!

N is the rate of compression in the storage matrix Eliminating all elements less than N = 4

Using our Mathematica program to produce the image matrix and compress it

Original digital image N=4 Compressed Image Matrix 29 Pieces of data – Much less to store, Still looks good.

21 Pieces of data – Still looks fairly good Original digital image N=8 Compressed Image Compressed Matrix 21 Pieces of data – Still looks fairly good
