基于稀疏模型的图像去噪算法研究

引入稀疏编码思想实现对数据信息的最优非线性逼近,在图像去噪方面已取得较好的实验效果。本文对图像去噪模型进行分析,介绍了稀疏编码思想实现图像去噪的原理,并对经典的稀疏去噪模型进行对比与分析。最后,基于稀疏模型对去噪算法进行分析,提出了稀疏模型在其他研究领域的展望。

The sparse coding can achieve the optimal nonlinear approximation of data information,and has achieved good experimental r esults in image denoising.This paper t hrough analyze t he image denoising,introduce t he principle of image denoising by sparse coding,and understand and analyze the classical image denoising methods based on the sparse model.Finally,based on the sparse model,the denoising algorithm is analyzed,and the prospect of sparse model in other research f ields is proposed.
