Abstract

In this letter, we propose a new edge-preserving smoothing filter, the cuboid filter. Since many applications for image processing and computer vision are based on the idea of denoising and extracting edges, the edge-preserving smoothing filter can be utilized in many applications, such as high dynamic range image compression, unsharp masking, stylization, and more. For this reason, various edge-preserving smoothing filters, such as the bilateral filter, the guided filter, and the domain transform, have been proposed. In general, these filters face a trade-off relationship between denoising performance and computational speed. The cuboid filter calculates only the mean of 3-dimensional neighboring pixels. The cuboid filter performs satisfactorily in reducing small-amplitude noise and fast filtering. On the basis of qualitative and quantitative evaluations, the effectiveness and the validity of the cuboid filter are shown.

长方体滤波器:简单的边缘保持平滑
在这封信中,我们提出了一种新的边缘保持平滑滤波器,长方体滤波器。由于图像处理和计算机视觉的许多应用都是基于去噪和提取边缘的思想,因此边缘保持平滑滤波器可以用于许多应用,如高动态范围图像压缩、锐化掩模、风格化等。出于这个原因,已经提出了各种边缘保持平滑滤波器,例如双边滤波器、引导滤波器和域变换。通常,这些滤波器面临去噪性能和计算速度之间的权衡关系。长方体滤波器仅计算三维相邻像素的平均值。长方体滤波器在减小小幅度噪声和快速滤波方面表现令人满意。在定性和定量评价的基础上,给出了长方体滤波器的有效性和有效性。
