Edge-Preserving Image Upsampling and Image Warping
… is to produce sharp and stylized upsampled images. We present cumulative range geodesic filter and bilateral roundup filter, with the former excels at edge sharpening and the latter finds a better balance between edge sharpening and fine-detail preservation. Moreover, we propose a pixel …

Distortion Correction for Non-Planar Deformable Projection Displays through Homography Shaping and Projected Image Warping
… correcting geometric distortions occurring when images or video frames are projected onto static and deformable non-planar display surfaces. The distortion-correction process involves (i) detecting feature points from the camera images and creating a desired shape of the undistorted view through …

Analyzing and synthesizing deformations in image datasets
… tasks in computer vision and graphics, such as image registration, optical flow estimation and image warping, are concerned with measuring spatial deformations between images. Traditional algorithms for these applications often rely on solving an optimization problem for each test input. Some of …

A feature-based fingerprinting scheme robust to desynchronization
… media copyrights. However, current schemes for image and video fingerprinting lack robustness against geometric attacks. We propose a novel semi-blind fingerprinting scheme that can cope with such attacks. The scheme improves a state-of-the-art high-rate fingerprinting code that can resist tens …

2D and 3D surface image processing algorithms and their applications
… work aims to develop algorithms for 2D image segmentation application of solar filament disappearance detection, 3D mesh simplification, and 3D image warping in pre-surgery simulation. Filament area detection in solar images is an image segmentation problem. A thresholding and region …

Multiresolution fixation of a binocular vision system
… procedure that can locate fixation points in an image pair. The binocular fixation procedure which has been developed here combats several difficult fixation problems that are hard to overcome with traditional approaches. Examples of this are objects lacking in visual texture, scenes with …

Scalable self-calibrating display technology for seamless large-scale displays
… gradients of an aggregated set of low-cost image display devices using a precision low cost reference. Use of the reference allows the construction of a locally correct map relating the coordinate system of the aggregate display to the coordinate systems of the individual projectors …

Real-Time Roadway Mapping and Ground Robotic Path Planning Via Unmanned Aircraft
… in order to map an area via UAV aerial imagery and aid a UGV in navigating a roadway when the road conditions are not previously known (i.e. disaster situations). Feature detection was used for transform calculation and image warping to create mosaics. A continuous extension using …

A low latency remote rendering system for interactive mobile graphics
… in real-time. My design takes advantage of an image based rendering technique: 3D image warping, to synthesize the final display image on the client from the multiple depth image references generated on the server. This Multi Depth Image approach can successfully reduce the interaction latency …

Constrained parameterization with applications to graphics and image processing.
… has been widely applied to computer graphics and image processing fields. The challenging issue is that the usual positional constraints always result in triangle flipping in parameterizations (also called foldovers). Additionally, distortion is inevitable in parameterizations. Thus the rigid …

Learning and Exploiting Camera Geometry for Computer Vision
… in scenarios with significant perspective warping. Methods are presented that allow the inverse perspective mapping traditionally applied to images to be applied instead to features computed from those images. For the special case of HOG-like features, which are used by many modern object …

Image Vectorization
… vector graphic from an object in a raster image. Object selection is performed interactively in subsecond time by calling graph cut with each mouse movement. A renderable mesh is then computed automatically for the selected object and each of its (sub)objects by (1) generating a coarse …
