Application of Hybrid Fractal Image Compression Method for Aerial Photographs

This paper proposes a method to improve the performance of Fractal lmage Compression (FIC) technique by combining FIC (lossy compression) and another lossless method (in this case Huffman coding is used). This proposed method takes advantage on each techniques, the high compression ratio that can be provided by FIC and the infinite peak-to-peak signal to-noise ratio (PSNR) that can be provided by lossless compression method. The experiment results show that with this hybrid FIC, we can get an infinite PSNR (no data losses) with higher compression ratio comparing to usual lossless method. It is expected that this method is suitable for compressing aerial photograps in terms of image reconstruction quality, compression ratio and processing time. This improvement is considerably interesting because we can save the storage space and data transmission time without any data losses.
