Depth Image Upsampling based on Guided Filter with Low Gradient Minimization

no code implementations12 Nov 2018 Hang Yang, Zhongbo Zhang

In our framework, the upscaling of a low-resolution depth image is guided by a corresponding intensity images, we formulate it as a cost aggregation problem with the guided filter.

Guided Filter based Edge-preserving Image Non-blind Deconvolution

no code implementations7 Sep 2016 Hang Yang, Ming Zhu, Zhongbo Zhang, He-Yan Huang

In the denoising step, the guided filter is used with the two obtained images for efficient edge-preserving filtering.

An Adaptive Parameter Estimation for Guided Filter based Image Deconvolution

no code implementations6 Sep 2016 Hang Yang, Zhongbo Zhang, Yujing Guan

Image deconvolution is still to be a challenging ill-posed problem for recovering a clear image from a given blurry image, when the point spread function is known.
