基于耦合映像格子模型的图像编码技术

Image Coding Technology Based on Coupled Map Lattice Model

提出应用耦合映像格子(CML)模型来进行预测编码。创新之处在于应用CML模型来进行预测编码而非已广泛应用的图像加密。用差值图像的熵来衡量不同模型的编码效率。仿真结果证明,新方法与JPEG标准中的方法相比,具有更高的预测精度,但编码效率稍有下降。

A new method for coding prediction is proposed,which is based on Coupled Map Lattice(CML) model.The novelty of the method proposed resides in CML′s application in image predication,instead of image encryption which is widely used.The simulation results indicate that this novel method shows that the new method has much better performance on prediction precision than JPEG at the cost of slight deterioration of coding efficiency represented by entropy.
