Because of its robustness, user friendliness, low cost and high accuracy, palmprint recognition has been widely studied in the past ten years. Various feature extraction and matching schemes have been proposed, among which the Gabor phase and orientation codes are very effective and efficient for palmprint representation and matching. Although these methods are adopted in the online palmprint recognition...
Traditional planar shape representations cannot efficiently solve some problems such as recognition under occlusion, reconstruction and partial matching. In this paper, an improved shape representation by the extraction of contour curvature is presented based on the invariance of curvature. Then the invariance and discrete approximation solution are demonstrated. Finally the reconstruction method...
KLT algorithm has been widely used in the registration process for natural features tracking in augmented reality (AR) systems. However, KLT is vulnerable by surrounding environments, and the feature points on screen borderlines or once be occluded may not be tracked persistently. Homographic matrices cannot be calculated accurately due to these disadvantages, which will result in registration failure...
