The gesture recognition systems are employed in developing a rock-paper-scissors game between human and our robotic hands in realtime. Our task is to predict the gestures as soon as possible by using high-speed cameras. Due to the computational complexity, the standard long-term recurrent convolution network-based action classification system cannot be contented with classification tasks based on high-speed cameras. We propose to address this issue by employing a more efficient network architecture and using a threshold-based method to predict the gesture in advance. We validate our proposed method on the new gesture dataset for the rock-paper-scissors game. The model is able to successfully learn gestures varying in duration and complexity. A comparative analysis of CNN and long-term recurrent convolution network is performed. We report a gesture classification accuracy of 97% and report a near real-time computational complexity of 7 ms per frame.\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-7a56429b e-flex e-con-boxed e-con e-parent\"

this paper, we propose a vision-based hand gesture recognition system for human-computer interaction. The gesture recognition systems are employed in developing a rock-paper-scissors game between human and our robotic hands in realtime. Our task is to predict the gestures as soon as possible by using high-speed cameras. Due to the computational complexity, the standard long-term recurrent convolution network-based action classification system cannot be contented with classification tasks based on high-speed cameras. We propose to address this issue by employing a more efficient network architecture and using a threshold-based method to predict the gesture in advance. We validate our proposed method on the new gesture dataset for the rock-paper-scissors game. The model is able to successfully learn gestures varying in duration and complexity. A comparative analysis of CNN and long-term recurrent convolution network is performed. We report a gesture classification accuracy of 97% and report a near real-time computational complexity of 7 ms per frame.<\/p>\n","protected":false},"author":1,"featured_media":1665,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[29],"tags":[],"class_list":["post-1664","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cv"],"_links":{"self":[{"href":"https:\/\/tongjicdi.com\/index.php\/wp-json\/wp\/v2\/posts\/1664","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tongjicdi.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tongjicdi.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tongjicdi.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/tongjicdi.com\/index.php\/wp-json\/wp\/v2\/comments?post=1664"}],"version-history":[{"count":4,"href":"https:\/\/tongjicdi.com\/index.php\/wp-json\/wp\/v2\/posts\/1664\/revisions"}],"predecessor-version":[{"id":1673,"href":"https:\/\/tongjicdi.com\/index.php\/wp-json\/wp\/v2\/posts\/1664\/revisions\/1673"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/tongjicdi.com\/index.php\/wp-json\/wp\/v2\/media\/1665"}],"wp:attachment":[{"href":"https:\/\/tongjicdi.com\/index.php\/wp-json\/wp\/v2\/media?parent=1664"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tongjicdi.com\/index.php\/wp-json\/wp\/v2\/categories?post=1664"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tongjicdi.com\/index.php\/wp-json\/wp\/v2\/tags?post=1664"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
