Abstract

Wavelet Image processing is applied in micro gravity combustion experiments.After processing of dynamic image of V flame in micro gravity, the information of the structure and instability of flame is distilled and analyzed.Therefore, it is implemented to investigate the structure and instabilities of flame through processing continuously dynamic image.
