An algorithm of neighbor relationship oriented contour tree building

Guo Peipei,Li Chengming,Yin Yong

Strategic Study of CAE 2013, Volume 15, Issue 5, Pages 42-46

Abstract:

A contour tree has been found many important applications in extractionA regular contour tree expressing the spatial relationship of contours is difficult to build, even withA new method is proposed in this paper： classify contours into close group and open group; build contourtree for each group respectively; finally amalgamate these two contour trees into one.

Image automatic mosaics based on contour phase correlation

ZHANG Jing, HU Zhiping, OU Zongying, LIU Zhitai

Frontiers of Mechanical Engineering 2007, Volume 2, Issue 2, Pages 228-234 doi: 10.1007/s11465-007-0040-8

Abstract: The image planar mosaics is studied, and an image automatic mosaics algorithm on the basis of contourTo begin with, by taking into account mere translations and rotations between images, a contour phaseThe contour phase correlation is an improvement on the conventional phase correlation in two aspects:

Chord error constraint based integrated control strategy for contour error compensation

Tie ZHANG, Caicheng WU, Yanbiao ZOU

Frontiers of Mechanical Engineering 2020, Volume 15, Issue 4, Pages 645-658 doi: 10.1007/s11465-020-0601-7

Abstract: the traditional cross-coupling control method cannot meet the requirements for tracking accuracy and contourcontrol accuracy in large curvature positions, an integrated control strategy of cross-coupling contourTo reduce the contour error, a PI-type cross-coupling controller is designed, with its stability beinganalyzed by using the contour error transfer function.control accuracy in biaxial contour following tasks.

A multiscale-contour-based interpolation framework for generating a time-varying quasi-dense point cloud

Chu-hua HUANG,Dong-ming LU,Chang-yu DIAO

Frontiers of Information Technology & Electronic Engineering 2016, Volume 17, Issue 5, Pages 422-434 doi: 10.1631/FITEE.1500316

Abstract: hardware platform, we propose an efficient framework to reconstruct 3D dynamic objects using a multiscale-contour-basedOur framework takes full advantage of spatio-temporal-contour consistency.model, and two contours which belong to the same view at different times, corresponding to point-, contour

Extracting hand articulations from monocular depth images using curvature scale space descriptors

Shao-fan WANG,Chun LI,De-hui KONG,Bao-cai YIN

Frontiers of Information Technology & Electronic Engineering 2016, Volume 17, Issue 1, Pages 41-54 doi: 10.1631/FITEE.1500126

Abstract: We extract the hand contour from an input depth image, and obtain the fingertips and finger-valleys ofthe contour using the local extrema of a modified CSS map of the contour.the undetected fingertips according to the local change of depths of points in the interior of the contour
