Genetic Algorithms (GA), Quantization Table (Q-Table),
and Natural Selection.
In several situations, images are processed in JPEG
standard with a Quantization Table without any
knowledge of where does the coefficient come from, and
there is little literature to produce a robust quantization
table. The fidelity loss in JPEG coding occurs entirely in
quantization , and it becomes very important to the
compression/fidelity performance of JPEG coding.
The proposal of this article is to generate a
Quantization Table that is more robust for medical images
using Genetic Algorithms method where the Signal Noise
Relation and Median Quadratic Error are observed in
each image as a parameter of the quality of the
