Journal ArticleDOI
Affine iterative closest point algorithm for point set registration
TL;DR: A novel generalized ICP algorithm based on lie group for affine registration of m-D point sets based on singular value decomposition technique, which decomposes affine transformation into three special matrices which are then constrained.
Proceedings ArticleDOI
Gait History Image: A Novel Temporal Template for Gait Recognition
Jianyi Liu,Nanning Zheng +1 more
TL;DR: An improved temporal template called gait history image (GHI) is proposed for human gait representation and recognition and presented better recognition performances than the baseline algorithm and gait energy image (GEI) method.
Journal ArticleDOI
Fast communication: Hybrid constraint SVR for facial age estimation
TL;DR: F fuzzy age label is firstly defined, and it is then merged into the Support Vector Regression framework together with the traditional data labels, and the new learning problem is formulated into a similar dual form with the standard SVR, which can be easily solved using existing solvers.
Journal ArticleDOI
Pose-and-illumination-invariant face representation via a triplet-loss trained deep reconstruction model
TL;DR: A new residual based deep face reconstruction neural network to extract discriminative pose-and-illumination-invariant features and achieves 83.8% average recognition accuracy on MultiPIE face dataset which is competitive to the state-of-the-art face recognition methods.
Journal ArticleDOI
Silhouette quality quantification for gait sequence analysis and recognition
TL;DR: In this paper, a silhouette quality quantification (SQQ) method is proposed to assess the quality of silhouette sequence and two instantiations of the SQW algorithm based on gait energy image (GEI) are implemented.
