1 “BBO based Fractal Compression using Medical Images”

Abstract — Image compression is a method through which we can reduce the storage space of images, videos and is helpful to increase storage and transmission process’s performance. Fractal compression is a lossy compression method for digital images, based on fractals. The major problem with fractal-based coding techniques is that of complexity at the encoding stage. Fractal image compression is time consuming in the encoding process. There are many optimization techniques which are used to improve efficiency of fractal image compression. The technique biogeography based optimization (BBO) is applied for fractal image compression (FIC).With the help of this algorithm effort is made to reduce the search complexity of matching between range block and domain block. FIC involves more computational time due to global search and it is its main drawback. So to improve the computational time and also the satisfactory quality of the decoded image, BBO algorithm is used in this work
