Abstract

In this paper, a novel patch-based modelling approach is proposed to augment the 3D models over the non-planar structure of hand. We present a robust real-time framework which first segment the hand using skin color information. To offer the subjects flexible interface (i.e., no restriction of covered arm), segmented skin-region is refined through distance descriptor which gives the hand’s palm. Next, we measure the geometrical components from the hand’s structure and compute the hand’s curvature to detect the fingertips. The palm centroid and detected fingertips contribute to the patch-based modelling for which optimal path is derived for every detected fingertip. Further, we compute the patches using the path points for every two neighbor detected fingers and then the camera poses are estimated for these patches. These different camera poses are finally combined to generate a single camera pose, and then 3D models are augmented on non-planar hand geometry. The experimental results show that our proposed approach is capable to detect hand, palm centroid and fingertips, as well as integrate the generated patches for augmented reality application in real situations which proves its applicability and usability in the domain of Human Computer Interaction.
