The amount of transmitted, stored and accessed information by
computers have been growing exponentially on the last decades. Two factors have
contributed to this effect, one is the appearing of the multimedia systems with its
variety of applications. The other is all that fact that nowadays computers not only
operate texts and numbers but sounds, images, movies and virtual reality. Inside this
scenario of new reality, we can also find, the development and the growth of the
internet availability (World Wide Web), an interactive and multimedia system based
on information, making this information available for a great quantity of users, with
stressed interactivity. This work shows the development of a system for digital
images Compression with base on Huffman and Wavelets procedures of data
storage and transmission in environments using digital images processing. It was
developed on the C++ language under Windows environment. For results validation
there were used standard images patterns of digital image Processing, as the Lena
and Girl image, both on 128x128, 256x256 and 512x512 pixels resolutions, as well
as tomographics images of soil and wood sample from tomograph of the Brazilian
Agricultural Research Corporation.
