In this paper, we tackle advantages of cyclical movement patterns of hand gestures. The cyclical patterns are defined as closed-form which hand moves away from a rest position, follows one or more of a series of the movement of hand shapes and returns to its rest position. Due to the cyclical pattern characteristic, phase of gestures are supportive cues for deploying robust recognition schemes. We...
Phase synchronization issue, that is caused by spotting gestures from video stream, varying frame-rates, speed of subject's implementation, should be overcome in developing Human-Computer Interaction (HCI) application using dynamic hand gestures. This paper tackles an interpolation technique to efficiently solve this issue. We firstly propose a new representation of dynamic hand gestures space that...
This paper presents a robust and real-time hand posture recognition system. To obtain this, key elements of the proposed system contain an user-guide scheme and a kernel-based hand posture representation. We firstly describe a three-stage scheme to train an end-user. This scheme aims to adapt environmental conditions (e.g., background images, distance from device to hand/human body) as well as to...
This paper argues that an user-guide plays an important role to make a robust and real-time hand posture recognition system. Instead of designing a new hand posture recognition algorithm, we propose an user-guide scheme which handles issues of environmental conditions as well as appearance-based features for hand detections. This guide estimates heuristic parameters whose values strongly affect the...
