Shape matching algorithm based on shape contexts
IET Computer Vision, 2015 This study proposes a novel shape matching algorithm through exploiting shape contexts. The contributions of the proposed algorithm are twofold: (i) a new framework is presented to deal with the shape matching problem based on shape contexts, but ...

Part-to-full shape matching of different human subjects [PDF]
Heliyon, 2021 Shape matching is a fundamental operation in digital geometry processing and computer graphics. Challenges in shape matching include finding correspondences of partial shapes with deformations, as well as topological noise and ambiguities.

Multisensory Perceptual Biases for Social and Reward Associations
Frontiers in Psychology, 2021 Linking arbitrary shapes (e.g., circles, squares, and triangles) to personal labels (e.g., self, friend, or stranger) or reward values (e.g., £18, £6, or £2) results in immediate processing benefits for those stimuli that happen to be associated with the

SMART GESTURE USING REAL TIME OBJECT TRACKING [PDF]
ICTACT Journal on Image and Video Processing, 2019 Gesture can be used to interact with the computer without any physical contact. The use of keyboard and mouse can be minimized. Gesture can be of various types. One such type is movement of hand in a particular posture.

Shape-Based Image Matching Using Heat Kernels and Diffusion Maps [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014 2D image matching problem is often stated as an image-to-shape or shape-to-shape matching problem. Such shape-based matching techniques should provide the matching of scene image fragments registered in various lighting, weather and season conditions or ...

Curvature-Based Machine Vision Method for Measuring the Dimension of Ball Screws
IEEE Access, 2023 As a linear actuator, accurate dimension measurement is crucial to the transmission reliability and interchangeability of ball screws. However, most of the current approaches are ineligible for rapid ball screw in-situ inspections due to the installation

Integral Invariants for Shape Matching [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2006 For shapes represented as closed planar contours, we introduce a class of functionals which are invariant with respect to the Euclidean group and which are obtained by performing integral operations. While such integral invariants enjoy some of the desirable properties of their differential counterparts, such as locality of computation (which allows ...

Canonical Skeletons for Shape Matching [PDF]
18th International Conference on Pattern Recognition (ICPR'06), 2006 Skeletal representations of 2-D shape, including shock graphs, have become increasingly popular for shape matching and object recognition. However, it is well known that skeletal structure can be unstable under minor boundary deformation, part articulation, and minor shape deformation (due to, for example, small changes in viewpoint).
