Image warping by scanline operations
Computers & Graphics, 1993Abstract Linear spatial image warping operations realized as 2 × 2 matrix multiplications lead to difficult computational problems owing to problems with sampling, resampling, and aliasing. A three-step method is proposed that minimizes these problems. Parallel implementation of the method is discussed. Examples are given.

Parallax-Tolerant Image Stitching Based on Robust Elastic Warping
IEEE transactions on multimedia, 2018Image stitching aims at generating high-quality panoramas with the lowest computational cost. In this paper, we propose a parallax-tolerant image stitching method based on robust elastic warping, which could achieve accurate alignment and efficient ...

GenWarp: Single Image to Novel Views with Semantic-Preserving Generative Warping
Neural Information Processing SystemsGenerating novel views from a single image remains a challenging task due to the complexity of 3D scenes and the limited diversity in the existing multi-view datasets to train a model on.

Image warps for artistic perspective manipulation
ACM SIGGRAPH 2010 papers, 2010Painters and illustrators commonly sketch vanishing points and lines to guide the construction of perspective images. We present a tool that gives users the ability to manipulate perspective in photographs using image space controls similar to those used by artists. Our approach computes a 2D warp guided by constraints based on projective geometry.

Graphical Models and Image Processing, 1998
An image warping method is presented that deforms an image continuously without foldover, while observing a given set of trajectories of feature elements. Any intermediate image during the morph is homeomorphic to the initial image and the morphing process is a homotopy.

WaSP: Hierarchical Warping, Merging, and Sparse Prediction for Light Field Image Compression
European Workshop on Visual Information Processing, 2018We propose a versatile light field compression scheme that is organized on hierarchical levels, where all views belonging to a particular level are encoded using several views already encoded in the previous hierarchical levels.

Enabling warping on stereoscopic images
ACM Transactions on Graphics, 2012Warping is one of the basic image processing techniques. Directly applying existing monocular image warping techniques to stereoscopic images is problematic as it often introduces vertical disparities and damages the original disparity distribution. In this paper, we show that these problems can be solved by appropriately warping both the disparity map

Image warping refers to the 2D resampling of a source image onto a target image. Despite the variety of techniques proposed, a large class of image warping problems remains inadequately solved: mapping between two images which are delimited by arbitrary, closed, planar curves, e.g., handdrawn curves.

Dynamic warping of seismic images
GEOPHYSICS, 2013The problem of estimating relative time (or depth) shifts between two seismic images is ubiquitous in seismic data processing. This problem is especially difficult where shifts are large and vary rapidly with time and space, and where images are contaminated with noise or for other reasons are not shifted versions of one another. A new solution to this

An image warping approach to image sequence interpolation
Proceedings of 1st International Conference on Image Processing, 2002Describes a new method for image sequence interpolation. The approach uses a feature-based image warping algorithm to align linear image features in two or more key frames. We propose modifications to this feature-based warping algorithm which reduce artifacts created in the presence of large distortions.
