Feather-Light Fourier Domain Adaptation in Magnetic Resonance Imaging

1 code implementation31 Jul 2022 Ivan Zakazov, Vladimir Shaposhnikov, Iaroslav Bespalov, Dmitry V. Dylov

Generalizability of deep learning models may be severely affected by the difference in the distributions of the train (source domain) and the test (target domain) sets, e. g., when the sets are produced by different hardware.

Domain Adaptation

Data Augmentation with Manifold Barycenters

no code implementations2 Apr 2021 Iaroslav Bespalov, Nazar Buzun, Oleg Kachan, Dmitry V. Dylov

Oftentimes, these methods either fail to produce enough new data or expand the dataset beyond the original knowledge domain.

Global Adaptive Filtering Layer for Computer Vision

no code implementations2 Oct 2020 Viktor Shipitsin, Iaroslav Bespalov, Dmitry V. Dylov

We devise a universal adaptive neural layer to "learn" optimal frequency filter for each image together with the weights of the base neural network that performs some computer vision task.

BRULÈ: Barycenter-Regularized Unsupervised Landmark Extraction

no code implementations20 Jun 2020 Iaroslav Bespalov, Nazar Buzun, Dmitry V. Dylov

Unsupervised retrieval of image features is vital for many computer vision tasks where the annotation is missing or scarce.
