Journal ArticleDOI
Scaling iterative closest point algorithm for registration of m-D point sets
TL;DR: A novel approach named the scaling iterative closest point (SICP) algorithm which integrates a scale matrix with boundaries into the original ICP algorithm for scaling registration of m-D point sets is introduced.
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.
Proceedings ArticleDOI
Facial Expression Sequence Synthesis Based on Shape and Texture Fusion Model
TL;DR: A Statistical Shape and Radio texture fusion model for facial expression sequence synthesis is proposed that is more expressive and realistic than traditional methods, and can process batch input well.
Proceedings ArticleDOI
Illumination transition image: Parameter-based illumination estimation and re-rendering
TL;DR: An improved illumination re-rendering method based on more accurate mapping of facial images in the parametric illumination space is proposed, which outperforms the quotient image approach on both parameter precision and rendering quality.
Proceedings ArticleDOI
Extended facial expression synthesis using statistical appearance model
TL;DR: The proposed method can synthesize a wider range of expressions than the training set have and experimental demonstrate that FCM is better than standard AAM in face representation.
