基于混合变分模型的图像去噪
Image denoising based on hybrid variational filter model
摘要
Abstract
In order to restrain the noise and obtain better visual effect, a novel image denoising method is proposed based on hybrid variation model. The harmonic model and the total variation model are integrated to enhance the filtering perfor-mance, and then the parameters are adaptively selected. When combinatorial coefficient is large, hybrid model is close to total variation model, and when combinatorial coefficient is small, hybrid model is close to harmonic model to effectively remove the staircase effect to protect the edge detail. The simulation experiment is carried out to test performance of model. The results show that, compared with other denoising models, the proposed model has better denoising effect and can better protect edge information under the same conditions.关键词
