In this paper, we propose a novel hand shape recognition method named as Coherent Distance Shape Contexts (CDSC), which is based on two classical shape representations, i.e., Shape Contexts (SC) and Inner-distance Shape Contexts (IDSC). CDSC has good ability to capture discriminative features from hand shape and can well deal with the inexact correspondence problem of hand landmark points. Particularly,...
In this paper, two perceptually motivated morphological strategies (PMMS) are proposed to enhance the retrieval performance of common shape matching methods. Firstly, two human perception customs are introduced, which have important relations to shape retrieval. Secondly, these two customs are properly modeled by morphological operations. Finally, the proposed PMMS is applied to improve the retrieval...
