Embedding Bilateral Filter in Least Squares for Efficient Edge-preserving Image Smoothing
Wei Liu, Pingping Zhang, Xiaogang Chen +3
Edge-preserving smoothing is a fundamental procedure for many computer vision and graphic applications. This can be achieved with either local methods or global methods. In most ca…
Edge-Preserving Piecewise Linear Image Smoothing Using Piecewise Constant Filters
Wei Liu, Wei Xu, Xiaogang Chen +3
Most image smoothing filters in the literature assume a piecewise constant model of smoothed output images. However, the piecewise constant model assumption can cause artifacts suc…
Robust Guided Image Filtering
Wei Liu, Xiaogang Chen, Chunhua Shen +3
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 betwee…
Robust High Quality Image Guided Depth Upsampling
Wei Liu, Yijun Li, Xiaogang Chen +3
Time-of-Flight (ToF) depth sensing camera is able to obtain depth maps at a high frame rate. However, its low resolution and sensitivity to the noise are always a concern. A popula…
