A complementary local feature descriptor for face identification [PDF]

2012 IEEE Workshop on the Applications of Computer Vision (WACV), 2012
In many descriptors, spatial intensity transforms are often packed into a histogram or encoded into binary strings to be insensitive to local misalignment and compact. Discriminative information, however, might be lost during the process as a trade-off.

A Hybrid 3D Descriptor With Global Structural Frames and Local Signatures of Histograms

IEEE Access, 2018
An effective feature descriptor is important for the 3-D object recognition and reconstruction. This paper presents a novel 3-D Frame-signature of histograms of orientation (SHOT) descriptor which combines the global structural frame with local surface ...

A novel method for SIFT features matching based on feature dimension matching degree [PDF]

MATEC Web of Conferences, 2019
We proposes a method for fast matching SIFT feature points based on SIFT feature descriptor vector element matching. First, we discretize each dimensional feature element into an array address based on a fixed threshold value and store the corresponding ...

Binary Descriptor for Images Based on Adaboost [PDF]

Jisuanji gongcheng, 2016
Classic descriptors such as Scale Invariant Feature Transform(SIFT) and Speeded up Robust Feature(SURF) have some drawbacks in storage capacity and parameter adaptive learning,so a binary descriptor for images based on Adaboost is proposed,which can ...

Matching Algorithm of 3D Point Clouds Based on Multiscale Features and Covariance Matrix Descriptors

IEEE Access, 2019
The three-dimensional (3D) point cloud is one of the most promising tools for representing and identifying 3D objects. The critical step for matching is to find the appropriate feature descriptors.
