In this work, we propose a hybrid scheme that considers both weighted guided image filtering and the Sobel mask for accurate edge detection. The weighted guided image filtering enhances edges, while the Sobel mask is used for edge detection. We conducted experiments on a wide variety of images ...
Although guided image filtering (GIF) is known for preserving edges and fast computation, it may produce inaccurate outputs in depth map restoration. In this paper, a novel confidence-weighted GIF called mutual-structure weighted GIF (MSWGIF) is proposed, which replaces the mean filtering strategy...

The process of using one image to guide the filtering process of another one is called Guided Image Filtering (GIF). The main challenge of GIF is the structure inconsistency between the guidance image and the target image. Besides, noise in the target image is also a challenging issue ...
