Fast Multi-spectral Image Coding Algorithm Based on Fractal

It is need to carry on the compression to the remote sensing image for the speedy transmission and the effective memory remote sensing image. The multi-spectrum remote sensing image has the very strong relevance among spectrums. In multi-wave band image compression, to eliminate the spectrum relevance, both must consider to eliminate the statistical dependence, and to eliminate the structure relevance. According to the multi-wave band remote sensing image´s characteristic, this article proposed that one kind of four fork tree piecemeal, the match information pre-stores and first searches the match the fast fractal encoding method. Proved through algorithm realization and the experiment, this article proposed the method to enhance multi-spectrum remote sensing image the compression ratio, the reduction time of compression to have certain function.
