Directional Connectivity-based Segmentation of Medical Images

1 code implementation CVPR 2023 Ziyun Yang, Sina Farsiu

To this end, we propose a directional connectivity modeling scheme for segmentation that decouples, tracks, and utilizes the directional information across the network.

RetiFluidNet: A Self-Adaptive and Multi-Attention Deep Convolutional Network for Retinal OCT Fluid Segmentation

1 code implementation26 Sep 2022 Reza Rasti, Armin Biglari, Mohammad Rezapourian, Ziyun Yang, Sina Farsiu

Experimental results on the datasets prove the effectiveness of the proposed model in retinal OCT fluid segmentation and reveal that the suggested method is more effective than existing state-of-the-art fluid segmentation algorithms in adapting to retinal OCT scans recorded by various image scanning instruments.

Modeling Extremes with d-max-decreasing Neural Networks

no code implementations17 Feb 2021 Ali Hasan, Khalil Elkhalil, Yuting Ng, Joao M. Pereira, Sina Farsiu, Jose H. Blanchet, Vahid Tarokh

We propose a novel neural network architecture that enables non-parametric calibration and generation of multivariate extreme value distributions (MEVs).

Mesoscopic photogrammetry with an unstabilized phone camera

1 code implementation CVPR 2021 Kevin C. Zhou, Colin Cooke, Jaehee Park, Ruobing Qian, Roarke Horstmeyer, Joseph A. Izatt, Sina Farsiu

We present a feature-free photogrammetric technique that enables quantitative 3D mesoscopic (mm-scale height variation) imaging with tens-of-micron accuracy from sequences of images acquired by a smartphone at close range (several cm) under freehand motion without additional hardware.

Fisher Auto-Encoders

no code implementations12 Jul 2020 Khalil Elkhalil, Ali Hasan, Jie Ding, Sina Farsiu, Vahid Tarokh

It has been conjectured that the Fisher divergence is more robust to model uncertainty than the conventional Kullback-Leibler (KL) divergence.

Learning Partial Differential Equations from Data Using Neural Networks

1 code implementation22 Oct 2019 Ali Hasan, João M. Pereira, Robert Ravier, Sina Farsiu, Vahid Tarokh

We develop a framework for estimating unknown partial differential equations from noisy data, using a deep learning approach.

MimickNet, Matching Clinical Post-Processing Under Realistic Black-Box Constraints

1 code implementation15 Aug 2019 Ouwen Huang, Will Long, Nick Bottenus, Gregg E. Trahey, Sina Farsiu, Mark L. Palmeri

Image post-processing is used in clinical-grade ultrasound scanners to improve image quality (e. g., reduce speckle noise and enhance contrast).
