Here () denotes the distance between and after alignment with warping function , (,) is the distance between warping paths and defined by the area of the region bounded by and , and is a hyperparameter balancing the time series alignment cost term and warping function distance term.
The simplest application of image geometry correction is a specific case known as keystone distortion correction derived from Keystone effect.Keystone distortion gets its name from the symmetric trapezoidal distortion resulting from misaligned projector placement in the vertical dimension (although the term is generally applied to the non-symmetric quadrilateral shape that occurs from an off ...
In time series analysis, dynamic time warping (DTW) is an algorithm for measuring similarity between two temporal sequences, which may vary in speed. For instance, similarities in walking could be detected using DTW, even if one person was walking faster than the other, or if there were accelerations and decelerations during the course of an ...
IUPAC limits the definition to representations on a "graphical display device". [2] Ever since Dalton 's atoms and Kekulé 's benzene , there has been a rich history of hand-drawn atoms and molecules, and these representations have had an important influence on modern molecular graphics.
Image warping example. Image warping is the process of digitally manipulating an image such that any shapes portrayed in the image have been significantly distorted. Warping may be used for correcting image distortion as well as for creative purposes (e.g., morphing [1]). The same techniques are equally applicable to video.
Elastic matching can be defined as an optimization problem of two-dimensional warping specifying corresponding pixels between subjected images. References [ edit ]
In chemical graph theory and in mathematical chemistry, a molecular graph or chemical graph is a representation of the structural formula of a chemical compound in terms of graph theory. A chemical graph is a labeled graph whose vertices correspond to the atoms of the compound and edges correspond to chemical bonds.
Retrosynthetic analysis is a technique for solving problems in the planning of organic syntheses.This is achieved by transforming a target molecule into simpler precursor structures regardless of any potential reactivity/interaction with reagents.
