Fractal Image Decoding Based on Fixed-point Theorem of Controllable and Changeable Parameter
Ding Xuan-hao · 2008
The fractal decoding has the merit of simple and fast and so on.But according to the Banach'fixed-point theorem,each time the conventional decoding obtains the image that is iterated and transformed,which is not suitable for the situation of advancing transmission and demonstration,such as low bandwidth transmission.And manufacture of computer auxiliary animation,therefore it is necessary to improve it.On account of the fixed parameter,the control of the advancing theorem is also very limited.In order to be under better control,this article proposes fixed-point theorem of controllable and changeable parameter to decode based on the characteristic of fractal decoding.The experiment indicates that the method has better and bigger improvement compared to the original method.
