Compact descriptor for local feature using dominating centre‐symmetric local binary pattern

open access: yesIET Computer Vision, 2016
The authors propose a terse texture feature, called the dominant centre‐symmetric local binary pattern (DCSLBP), which has similar distinctiveness and half dimension compared against original centre‐symmetric local binary pattern (CS‐LBP).

PPTFH: Robust Local Descriptor Based on Point-Pair Transformation Features for 3D Surface Matching

open access: yesSensors, 2021
Three-dimensional feature description for a local surface is a core technology in 3D computer vision. Existing descriptors perform poorly in terms of distinctiveness and robustness owing to noise, mesh decimation, clutter, and occlusion in real scenes ...

Learning Spread-Out Local Feature Descriptors [PDF]

open access: yes2017 IEEE International Conference on Computer Vision (ICCV), 2017
We propose a simple, yet powerful regularization technique that can be used to significantly improve both the pairwise and triplet losses in learning local feature descriptors. The idea is that in order to fully utilize the expressive power of the descriptor space, good local feature descriptors should be sufficiently "spread-out" over the space.

Local Property of Depth Information in 3D Images and Its Application in Feature Matching

open access: yesMathematics, 2023
In image registration or image matching, the feature extracted by using the traditional methods does not include the depth information which may lead to a mismatch of keypoints.
