基于引导滤波的多分支注意力残差红外图像去噪网络

Multi-drop attention residual infrared image denoising network based on guided filtering

  • 摘要: 目前红外图像广泛应用于各个领域,但受限于探测单元的非均匀性,使得红外图像具有低信噪比、视觉效果模糊的缺点,严重影响其在高端领域中的应用。常用的去噪算法无法兼顾降噪平滑和边缘细节的保持,针对这一问题,文中提出了一种基于引导滤波的多分支注意力残差去噪网络。根据引导滤波原理设计一种引导卷积模块,同时为了兼顾提取浅层和深层特征设计了多分支注意力残差模组。通过实验证明加入新模块后的网络不仅可以有效地实现红外图像降噪,而且能最大程度地保持图像中的边缘细节信息,提升视觉效果,同时在PSRN和SSIM指标上也有良好的表现。

     

    Abstract: At present, infrared images are widely used in various fields, but limited by the non-uniformity of detector unit, the infrared image has the disadvantages of low signal-to-noise ratio and blurred visual effects, which seriously affect its application in advanced fields. Commonly used denoising algorithms cannot take into account the smoothing of denoising and the preservation of edge details. In response to the above problems, this paper proposes a multi-drop attention residual denoising network based on guided filtering. A guided convolution module is designed according to the principle of guided filtering and a multi-drop attention residual module is designed for both the extraction of shallow and deep features. Experiments have proved that the network after adding the new module can effectively reduce the noise of infrared images, and can maintain the edge detail information in the image to the greatest extent, improve the visual effect, and also have good performance on the PSRN and SSIM indicators.
