Local Log-Euclidean Covariance Matrix (L2ECM) for Image Representation and Its Applications

  title={Local Log-Euclidean Covariance Matrix (L2ECM) for Image Representation and Its Applications},
  author={Peihua Li and Qilong Wang},
This paper presents Local Log-Euclidean Covariance Matrix (LECM) to represent neighboring image properties by capturing correlation of various image cues. Our work is inspired by the structure tensor which computes the second-order moment of image gradients for representing local image properties, and the Diffusion Tensor Imaging which produces tensor-valued image characterizing the local tissue structure. Our approach begins with extraction of raw features consisting of multiple image cues… CONTINUE READING
