Image restoration of arbitrarily warped documents [PDF]

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2004
We present a framework for acquiring and restoring images of warped documents. The purpose of our restoration is to create a planar representation of a once planar document that has undergone an arbitrary and unknown rigid deformation. To accomplish this restoration, our framework acquires and flattens the 3D shape of a warped document to determine a ...

InterFace: A software package for face image warping, averaging, and principal components analysis

open access: yesBehavior Research Methods, 2016
We describe InterFace, a software package for research in face recognition. The package supports image warping, reshaping, averaging of multiple face images, and morphing between faces. It also supports principal components analysis (PCA) of face images,

Efficient C2-Weighting for Image Warping

open access: yesIEEE Computer Graphics and Applications, 2018
Handle-driven image warping based on linear blending is widely used in many applications because of its merits on intuitiveness, efficiency, and ease of implementation. In this paper, we develop a method to compute high-quality weights within a closed domain for image warping.

A Novel Robot Visual Homing Method Based on SIFT Features

open access: yesSensors, 2015
Warping is an effective visual homing method for robot local navigation. However, the performance of the warping method can be greatly influenced by the changes of the environment in a real scene, thus resulting in lower accuracy.

Image-based clothes changing system

open access: yesComputational Visual Media, 2017
Current image-editing tools do not match up to the demands of personalized image manipulation, one application of which is changing clothes in usercaptured images. Previous work can change single color clothes using parametric human warping methods.

A Comparison of Hyperelastic Warping of PET Images with Tagged MRI for the Analysis of Cardiac Deformation

open access: yesInternational Journal of Biomedical Imaging, 2013
The objectives of the following research were to evaluate the utility of a deformable image registration technique known as hyperelastic warping for the measurement of local strains in the left ventricle through the analysis of clinical, gated PET image ...

Application of the Warping Methods in Dental Radiology Images Analysis [PDF]

open access: yesApplied Medical Informatics, 2012
The “image warping” functions are useful techniques to match image objects when there are strong correlations between the positions of these objects in space. In order to do this, a function f, called warping function, is defined and is used to convert a

Image Warp Preserving Content Intensity

open access: yesSIAM Journal on Imaging Sciences, 2022
An accurate method for warping images is presented. Differently from most commonly used techniques, this method guarantees the conservation of the intensity of the transformed image, evaluated as the sum of its pixel values over the whole image or over corresponding transformed subregions of it. Such property is mandatory for quantitative analysis, as,

Multiple-image super-resolution on mobile devices: an image warping approach

open access: yesEURASIP Journal on Image and Video Processing, 2017
This paper discusses a super-resolution (SR) system implemented on a mobile device. We utilized an Android device’s camera to take successive shots and applied a classical multiple-image super-resolution (SR) technique that utilized a set of low ...
