Book ChapterDOI
High Accuracy Optical Flow Estimation Based on a Theory for Warping
TL;DR: By proving that this scheme implements a coarse-to-fine warping strategy, this work gives a theoretical foundation for warping which has been used on a mainly experimental basis so far and demonstrates its excellent robustness under noise.
Journal ArticleDOI
Mathematical morphology for matrix fields induced by the Loewner ordering in higher dimensions
TL;DR: This paper presents novel definitions for the supremum and infimum of a set of matrices since these notions lie at the heart of the morphological operations and introduces erosion, dilation, opening, closing, top hats, morphological derivatives, shock filters and mid-range filters for positive semidefinite matrix-valued images.
Book ChapterDOI
Morphology for Higher-Dimensional Tensor Data Via Loewner Ordering
TL;DR: The operators of greyscale morphology rely on the notions of maximum and minimum which regrettably are not directly available for tensor-valued data since the straightforward component-wise approach fails.
Mathematical morphology for tensor data induced by the Loewner orderingin higher dimensions
TL;DR: In this article, the authors extend fundamental morphological operations to the matrix-valued setting and introduce erosion, dilation, opening, closing, top hats, morphological derivatives, shock filters, and mid-range filters for positive semidefinite matrixvalued images.
