Real-time image fractal encoding based on GPU
Sun Don · Journal of Anhui University · 2014
Fractal image encoding can provide a high compression ratio with a high reconstructed image quality,but it suffers from long encoding time,so it is difficult to promote. A new scheme based on image-fractal(FW) encoding was proposed. Under the CUDA specification,GPU was used to search the best match parent-tree for each sub-tree parallel. Experiment results proved that the scheme could magnificently reduce encoding time to milliseconds-level with maintaining the reconstructed quality and the requirements of real-time was satisfied.
