基因表达式编程的自适应阈值去噪方法研究

摘要

提出将基因表达式编程应用于图像自适应阈值去噪，根据多尺度分辨率特性和基因表达式编程的全局搜索能力，构建搜索最小均方差的自适应阈值优化模型。实验结果表明，基于基因表达式编程的自适应阈值参数优化策略在图像去噪方面是可行的，并达到了较高的峰值信噪比。%We propose to apply gene expression programming ( GEP ) to image adaptive threshold denoising , and construct an adaptive threshold optimisation model for searching the minimum mean square error based on multi-scale resolution characteristic and global searching ability of GEP.Experimental results show that the GEP-based adaptive threshold parameters optimisation strategy is feasible in image denois-ing and achieves higher PSNR .
