Spatio-Temporal Dual Affine Differential Invariant for Skeleton-based Action Recognition
Qi Li, Hanlin Mo, Jinghan Zhao +2
The dynamics of human skeletons have significant information for the task of action recognition. The similarity between trajectories of corresponding joints is an indicating featur…
Dual affine moment invariants
You Hao, Hanlin Mo, Qi Li +2
Affine transformation is one of the most common transformations in nature, which is an important issue in the field of computer vision and shape analysis. And affine transformation…
Rotation Differential Invariants of Images Generated by Two Fundamental Differential Operators
Hanlin Mo, Hua Li
In this paper, we design two fundamental differential operators for the derivation of rotation differential invariants of images. Each differential invariant obtained by using the…
Image Projective Invariants
Erbo Li, Hanlin Mo, Dong Xu +1
In this paper, we propose relative projective differential invariants (RPDIs) which are invariant to general projective transformations. By using RPDIs and the structural frame of…
4d isip: 4d implicit surface interest point detection
Shirui Li, Alper Yilmaz, Changlin Xiao +1
In this paper, we propose a new method to detect 4D spatiotemporal interest points though an implicit surface, we refer to as the 4D-ISIP. We use a 3D volume which has a truncated…
A Kind of Affine Weighted Moment Invariants
Hanlin Mo, You Hao, Shirui Li +1
A new kind of geometric invariants is proposed in this paper, which is called affine weighted moment invariant (AWMI). By combination of local affine differential invariants and a…
Shape-Color Differential Moment Invariants under Affine Transformations
Hanlin Mo, Shirui Li, You Hao +1
We propose the general construction formula of shape-color primitives by using partial differentials of each color channel in this paper. By using all kinds of shape-color primitiv…
Reflection Invariant and Symmetry Detection
Erbo Li, Hua Li
Symmetry detection and discrimination are of fundamental meaning in science, technology, and engineering. This paper introduces reflection invariants and defines the directional mo…
Isomorphism between Differential and Moment Invariants under Affine Transform
Erbo Li, Hua Li
The invariant is one of central topics in science, technology and engineering. The differential invariant is essential in understanding or describing some important phenomena or pr…
Affine-Gradient Based Local Binary Pattern Descriptor for Texture Classiffication
You Hao, Shirui Li, Hanlin Mo +1
We present a novel Affine-Gradient based Local Binary Pattern (AGLBP) descriptor for texture classification. It is very hard to describe complicated texture using single type infor…
Naturally Combined Shape-Color Moment Invariants under Affine Transformations
Ming Gong, You Hao, Hanlin Mo +1
We proposed a kind of naturally combined shape-color affine moment invariants (SCAMI), which consider both shape and color affine transformations simultaneously in one single syste…
Shape DNA: Basic Generating Functions for Geometric Moment Invariants
Erbo Li, Yazhou Huang, Dong Xu +1
Geometric moment invariants (GMIs) have been widely used as basic tool in shape analysis and information retrieval. Their structure and characteristics determine efficiency and eff…
