Feature preserving smoothing of 3D surface scans
… scanned data, based on extensions of the bilateral filter to 3D. The bilateral filter is a non-linear, edge-preserving image filter; its extension to 3D leads to an efficient, feature preserving filter for a wide class of surface representations, including points and "polygon soups."

Improved Techniques for Video Compression and Communication
… improve compression performance by applying a bilateral filter in the motion compensated prediction. The bilateral filter can remove the noise while preserving the edges. Our experimental results show that adding the bilateral filter can achieve a 4.9%, 1.6%, 1.6% average gain, in H.265/HEVC …

Automatic 2D-to-3D conversion of single low depth-of-field images
… depth map is pre-smoothed using an asymmetric bilateral filter. Hole-filling of the remaining dis-occlusions is performed through nearest-neighbour horizontal interpolation, which incorporates depth as well as direction of warp. To minimising the effects of the lateral striations, specific …

Efficient data structures for piecewise-smooth video processing
… algorithms. We start by introducing the bilateral grid, an image representation that explicitly accounts for intensity edges. By interpreting brightness values as Euclidean coordinates, the bilateral grid enables simple expressions for edge-aware filters. Smooth functions defined on the …

Robust and efficient image-based 3D modeling
… I next propose a new framework based on bilateral filtering and loopy belief propagation for simultaneous estimation of surface reflectance and shape with the assumption that the illumination chromaticity can be correctly estimated. Two new bilateral filtering algorithms with …

Patch-based Denoising Algorithms for Single and Multi-view Images
… An adaptive collaborative thresholding filter is proposed which consists of a classification map and a set of various thresholding levels and operators. These are exploited when the collaborative hard-thresholding step is applied. Moreover, the collaborative Wiener filtering is improved …

Structure adaptive stylization of images and video
… Second, separable implementations of the popular bilateral and difference of Gaussians filters that adapt to the local structure are presented. These filters avoid artifacts while being computationally highly efficient. Taken together, both provide an effective way to create a cartoon-style …
