IMAGE STITCHING WITH PERSPECTIVE-PRESERVING WARPING [PDF]
ISPRS 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,

Image warp preserving content intensity [PDF]
SIAM 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,

Warped Discrete Cosine Transform-Based Low Bit-Rate Block Coding Using Image Downsampling [PDF]
EURASIP Journal on Advances in Signal Processing, 2007 This paper presents warped discrete cosine transform (WDCT)-based low bit-rate block coding using image downsampling. While WDCT aims to improve the performance of conventional DCT by frequency warping, the WDCT has only been applicable to high bit-rate

Estimating Myocardial Motion by 4D Image Warping. [PDF]
Pattern Recognit, 2009 A method for spatio-temporally smooth and consistent estimation of cardiac motion from MR cine sequences is proposed. Myocardial motion is estimated within a 4-dimensional (4D) registration framework, in which all 3D images obtained at different cardiac phases are simultaneously registered.
