An Efficient Method for Document Correction Based on Checkerboard Calibration Pattern
Applied Sciences, 2022 Portable digital devices such as PDAs and camera phones are the easiest and most widely used methods to preserve and collect information. Capturing a document image using this method always has warping issues, especially when capturing pages from a book ...

Polygonal finite element-based content-aware image warping
Computational Visual Media, 2023 Mesh-based image warping techniques typically represent image deformation using linear functions on triangular meshes or bilinear functions on rectangular meshes. This enables simple and efficient implementation, but in turn, restricts the representation

Metameric Inpainting for Image Warping
IEEE Transactions on Visualization and Computer Graphics, 2023 Image-warping, a per-pixel deformation of one image into another, is an essential component in immersive visual experiences such as virtual reality or augmented reality. The primary issue with image warping is disocclusions, where occluded (and hence unknown) parts of the input image would be required to compose the output image.

Enhancement by image-dependent warping [PDF]
IEEE Transactions on Image Processing, 1999 All image warping algorithms to date are image-independent, namely, relate only to the geometry of the image plane, ignoring the content of the image. We show that taking the image content into account yields elaborate warping schemes which may be used to enhance, sharpen and scale images.

Structure Preservation and Seam Optimization for Parallax-Tolerant Image Stitching
IEEE Access, 2022 Parallax processing has long been a significant and challenging task in image stitching. In this paper, we study a new hybrid warping model based on multi-homography and structure preservation to achieve accurate alignment of regions at different depths ...

Spatial and Time Warping for Gauge Adjustment of Rainfall Estimates
Atmosphere, 2021 Many satellite-based estimates use gauge information for bias correction. In general, bias-correction methods are focused on the intensity error and do not explicitly correct possible position or timing errors.

Image Warping Among Arbitrary Planar Shapes [PDF]
, 1988 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,

Image Stitching Based on Nonrigid Warping for Urban Scene
Sensors, 2020 Image stitching based on a global alignment model is widely used in computer vision. However, the resulting stitched image may look blurry or ghosted due to parallax.
