In this work of thesis there appears the development of a technology of codification to achieve
the compression of images satelitales, facilitating hereby his transmission on having used minor
bandwidth and minor time of transmission, as well as also facilitating his storage on having used
devices with minor capacity in bytes.
This project is characterized by the implementation of computational algorithms based on
the software Matlab, where one has developed two technologies of compression with the purpose
of reaching a high degree of compression without altering too much the information contained in
the image. They are two technologies combined that are in use in this thesis: the codification
with losses, and without losses.
The codification with losses is based on the use of transformed discreet of the cosine in 2D
(two dimensions), as the JPEG standard uses it, and the codification without losses based on the
use of the codification Huffman, where it is achieved to assign the minor quantity of bits for the
codification without losing any information.
This combination of technologies obtains valuable results especially in images satelitales
that are obtained by very poor resolutions in comparison with the conventional photographies
