A Self Adaptability based Stereo Correspondence of Face Images using Wavelets
نویسندگان
چکیده
This paper proposes a discrete wavelet-based stereo matching technique. A discrete wavelet transform is first applied to a pair of stereo images to decorrelate the images into a number of approximations. Information in the basebands is less sensitive to shift variability of the wavelet transform. A self-adapting dissimilarity measure is employed to generate a disparity map of the stereo pairs. Results show that the proposed technique produces smoother disparity maps with less computation cost.

متن کامل3D head model from stereo images by a self-organizing neural network
In this paper a model based approach is presented for generating 3D face models from two stereo images. The proposed method works with a small number of feature points of the face. The automatically registrated point pairs are used to reconstruct their 3D correspondence, then a predefined general face model is adjusted to the reconstructed 3D points. Fitting the general face model to the featur...
متن کاملStereo Video Disparity Estimation Using Multi-wavelets
Disparity estimation in stereo video processing is a crucial step in the generation of a 3D view of a scene. In this paper, a multi-wavelet based stereo correspondence matching technique for video is proposed. A multi-wavelet transform is first applied to a pair of stereo frames. Correspondence matching is initially performed at the coarsest level and relies on coarse-to-fine refinement in orde...
متن کاملGeneral Stereo Image Matching Using Symmetric Complex Wavelets
General stereo image matching provides an adequate but hard problem with suucient complexity, with which the potential of wavelets may be exploited to a full extent. An ideal stereo image matching algorithm is supposed to be invariant to the scale, translation, rotation, and partial correspondence between two given stereo images. While the multiresolution of wavelets is good at scale adaptivity...
