It is realized by disassembling the whole into parts and subsequently recombining them. In our research, the salient visual regions were firstly calculated in the views of the hearing-impaired person by simulating their cognitive mode about sign languages. Afterwards, the visual seeds of focus were concentrated on the hands to improve its effectiveness. Finally, we obtained the sub-sign language by making the generated semantic superpixels as the parts, which were mapped into the finger skeleton, or shrinking the palm to a node. By disassembling the images (states) of sign languages according to their anatomical structures, the visual semantic-structural parsing is preliminarily realized for a set of words of the similar sign language. | 查看全文查看/发表评论下载PDF阅读器 | |
