软硬件协同仿真在图像滤波器演化设计中的应用

针对传统图像滤波器设计方法存在的局限性，将演化硬件引入图像滤波器设计中，提出软硬件协同仿真的演化思想，并设计了基于System Generator的图像滤波器演化系统。通过图像滤波器演化实验验证了演化系统的有效性，实验结果及分析表明，最优演化滤波器在性能和实现代价方面均优于传统滤波器。与现有的图像滤波器演化方法相比，软硬件协同仿真的演化方法具有实现简单、运算能力强、功能灵活等优点。该系统的演化算法可综合成硬件，为后续实现在线自适应滤波奠定了基础。

Application of Soft Hardware Co Simulation in Evolutionary Design of Image Filters

Evolvable hardware is introduced to the design of image filters because of the limitations of traditional image filter design methods. An evolutionary method based on soft hardware co simulation is proposed. And an image filter evolvable system based on system generator is designed. Experiment is conducted to test the validity of the evolvable system, experimental results and analyses demonstrate that the optimal evolutionary filter outperforms traditional filters both in performance and implementation costs.In comparison with the existing evolutionary methods of image filter, the evolutionary method based on soft hardware co simulation brings higher computational ability and more flexibility. The evolutionary algorithm for the evolvable system can be synthesized into hardware to provide a basis for the follow up to achieve online adaptive filtering.
