Non-rigid Registration using Spectral Graph Wavelet FeaturesAuthors: Alphin J Thottupattu,Shivin Yadav,Avinash Sharma Conference: 11th Indian Conference on Computer Vision, Graphics and Image Processing (ICVGIP-2018 2018) Date: 2018-12-18 Report no: IIIT/TR/2018/82 AbstractImage registration is an essential step in many computer vision applications which demands high accuracy for significantly random and complex deformations. In medical image processing applications image registration is a basic preprocessing step to non-rigidly align images from different acquisition environments to an atlas image. We propose a novel non-rigid image registration method to get more reliable registration even under noisy conditions with manageable time complexity. The proposed method explores the the inherent multi-resolution capability of wavelets to perform nonrigid registration in a graph environment. The inherent time complexity of wavelet feature map calculation is avoided using Chebyshev Polynomial approximations for the wavelet operators.
