An Efficient Method for Document Correction Based on Checkerboard Calibration Pattern

open access: yesApplied 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

open access: yesComputational 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

Tilt Correction of Panoramic Images for a Holistic Visual Homing Method with Planar-Motion Assumption

open access: yesRobotics, 2023
Holistic local visual homing based on warping of panoramic images relies on some simplifying assumptions about the images and the environment to make the problem more tractable.

IMAGE STITCHING WITH PERSPECTIVE-PRESERVING WARPING [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
Image stitching algorithms often adopt the global transform, such as homography, and work well for planar scenes or parallax free camera motions. However, these conditions are easily violated in practice. With casual camera motions, variable taken views,

Structure Preservation and Seam Optimization for Parallax-Tolerant Image Stitching

open access: yesIEEE 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 ...

Locally Aligned Image Stitching Based on Multi-Feature and Super-Pixel Segmentation With Plane Protection

open access: yesIEEE Access, 2021
The number and accuracy of image feature matching directly affect the accuracy of image warping, which is gaining widespread attention in image stitching.

Spatial and Time Warping for Gauge Adjustment of Rainfall Estimates

open access: yesAtmosphere, 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 Stitching Based on Nonrigid Warping for Urban Scene

open access: yesSensors, 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.

Image Style Transfer via Multi-Style Geometry Warping

open access: yesApplied Sciences, 2022
Style transfer of an image has been receiving attention from the scientific community since its inception in 2015. This topic is characterized by an accelerated process of innovation; it has been defined by techniques that blend content and style, first ...

As-Aligned-As-Possible Image Stitching Based on Deviation-Corrected Warping With Global Similarity Constraints

open access: yesIEEE Access, 2019
Handling local misalignment caused by the local warp remains a common and challenging task for image stitching. Moreover, the stitched image is prone to appearing ghosting due to the variations of the image viewpoint between images.
