Resumo: | |||||||||||||
This work concerns with a technique for progressive image
transmission. The method bases on the Burt and Adelson
Pyramid Model. The method applies vector quantization to a
pyramid of difference images. These, result from the
subtraction of parts of the shuffled image. The decimated
image pixel represents the mean value of four neighboring
pixels ot the original image, partitioned in 2x2 blocs of
pixels. This decimated image is a mean image and their
set also constitutes itself a pyramid. At each new
pyramided level, the considered original image is the
mean image of the previous level.
The progressive image transmission is by sending first the
highest level difference image (with the minimum number of
pixels) up to the lowest difference image level.
The work also includes results comparison to other
literature know methods in terms of peak signal to noise
ratio, subjective quality and computational effort.
