Multi-task Learning for Optical Coherence Tomography Angiography (OCTA) Vessel Segmentation

no code implementations3 Nov 2023 Can Koz, Onat Dalmaz, Mertay Dayanc

In this paper, we propose a novel multi-task learning method for OCTA segmentation, called OCTA-MTL, that leverages an image-to-DT (Distance Transform) branch and an adaptive loss combination strategy.

Learning Fourier-Constrained Diffusion Bridges for MRI Reconstruction

1 code implementation2 Aug 2023 Muhammad U. Mirza, Onat Dalmaz, Hasan A. Bedel, Gokberk Elmas, Yilmaz Korkmaz, Alper Gungor, Salman UH Dar, Tolga Çukur

Instead of the target transformation from undersampled to fully-sampled data required for MRI reconstruction, common diffusion priors are trained to learn a task-agnostic transformation from an asymptotic start-point of Gaussian noise onto the finite end-point of fully-sampled data.

ResViT: Residual vision transformers for multi-modal medical image synthesis

2 code implementations30 Jun 2021 Onat Dalmaz, Mahmut Yurt, Tolga Çukur

Here, we propose a novel generative adversarial approach for medical image synthesis, ResViT, that leverages the contextual sensitivity of vision transformers along with the precision of convolution operators and realism of adversarial learning.}
