Resumo:
This dissertation introduces a strategy to develop a compression method for sensor data inspired on the JPG2000 techniques. The strategy adopted processes data streams much in the same way as signal processing. Due to the unstable nature of sensor data, noise is added to the original signal. This noise is detected and treated while the signal is cleaned and smoothed, making it easier to analyze the data stream. Less relevant signal components are removed or approximated allowing the signal to be compressed with few information loss.
