Tensors in Image Processing and Computer Vision (Advances in Computer Vision and Pattern Recognition)

By Santiago Aja-Fernández, Rodrigo de Luis Garcia, Dacheng Tao, Xuelong Li

Tensor sign processing is an rising box with very important functions to machine imaginative and prescient and photo processing. This ebook provides the state-of-the-art during this new department of sign processing, providing loads of examine and discussions via major specialists within the zone. The wide-ranging quantity deals an summary into state of the art learn into the most recent tensor processing options and their software to various domain names with regards to desktop imaginative and prescient and snapshot processing. This entire textual content will turn out to be a useful reference and source for researchers, practitioners and complex scholars operating within the sector of desktop imaginative and prescient and snapshot processing.

Constitution of the bankruptcy. we begin via describing our variational version in part 2. We aspect at the power sensible and description the minimisation process. part three is dedicated to the experimental review. a sequence of experiments in 2nd on man made and DT-MRI information demonstrates easy good points of the strategy. through 3D experiments the viability of the procedure for 3D info is verified, and a comparability to a finite-strain dependent registration strategy is made. part four features a precis and outlook. 2 The Variational version within the following, we think about tensor fields R, T : Rd → SPD(d).
