To address these problems, in this study, we propose a novel domain adaptation method, referred to as discriminative invariant alignment (DIA), for image representation. DIA enriches the knowledge matrix by combining the class discriminative information of the source domain and local data structure ...
Deep learningDiscriminative modelFeature encodingLinear regressionFacial aging variation is a major problem for face recognition systems due to large intra-personal variations caused by age progression. A major challenge is to develop an efficient, discriminative feature representation and matching framework,...
Learning 3D skeleton based representation for gesture recognition has increasingly attracted attention due to its invariance to camera viewpoint and video environment dynamics. Existing methods typically utilize absolute coordinates to extract human motion features. However, gestures are independent of the ...
