This paper proposes a multiscale 3D keypoint detection method based on local weighted dissimilarity measure. At first, compute the local weighted dissimilarity measure of each vertex at different scale. Then determine the detecting scale of each vertex. Finally compare the local weighted dissimilarity measure of each vertex with those of its neighboring surface points at its detecting scale. The keypoint...
Ear recognition, by using ear for identification recognition, is a kind of new biometric identification technology. Currently there are a lot of ear recognition methods based on 2D images, while 3D data can provide more information. 3D reconstruction methods based on multiple 2D images have a common difficult which is to extract corresponding feature points of different images. In this paper, SFS(Shape...
This paper presents an automatic 3D ear reconstruction method based on binocular stereo vision. At first, we calibrate the stereo vision system by Zhang's method. Then the quasi-dense matching method is performed. We use SIFT feature based matching approach and the coarse to fine strategy to compute the seed matches. The adapted match propagation algorithm with known epipolar geometry constraint is...
We present a novel 3D ear reconstruction method based on epipolar geometry. First, we calibrate the camera system. Second, we apply Harris corner detector to extract feature points from the first image. For every feature point, we apply epipolar geometry constrain to draw epipolar line in the second image and search corresponding point on it. Both the feature point and points on the epipolar line...
