“…1 (a). In the past years, many grasp pattern recognition methods have been proposed, which have a great impact in several fields including robot imitation [1,2,3], human-robot interaction [4,5], human grasp predicting [6,7,8,9,10], prosthetic design [11,12,13], robot control [14,15,16,17,18], and prosthetic control [19,20,21]. In recent years, Convolutional Neural Network (CNN) [22,23] has shown excellent performance on many challenging tasks, such as object detection and tracking.…”
