CenTime: Event-Conditional Modelling of Censoring in Survival Analysis

2 code implementations7 Sep 2023 Ahmed H. Shahin, An Zhao, Alexander C. Whitehead, Daniel C. Alexander, Joseph Jacob, David Barber

We demonstrate that our approach forms a consistent estimator for the event model parameters, even in the absence of uncensored data.

From Sparse to Precise: A Practical Editing Approach for Intracardiac Echocardiography Segmentation

no code implementations20 Mar 2023 Ahmed H. Shahin, Yan Zhuang, Noha El-Zehiry

Furthermore, our framework accommodates multiple edits to the segmentation output in a sequential manner without compromising previous edits.

Survival Analysis for Idiopathic Pulmonary Fibrosis using CT Images and Incomplete Clinical Data

2 code implementations21 Mar 2022 Ahmed H. Shahin, Joseph Jacob, Daniel C. Alexander, David Barber

To this end, we propose a probabilistic model that captures the dependencies between the observed clinical variables and imputes missing ones.

FAIRS -- Soft Focus Generator and Attention for Robust Object Segmentation from Extreme Points

no code implementations4 Apr 2020 Ahmed H. Shahin, Prateek Munjal, Ling Shao, Shadab Khan

We propose a novel approach for effectively encoding the user input from extreme points and corrective clicks, in a novel and scalable manner that allows the network to work with a variable number of clicks, including corrective clicks for output refinement.

Extreme Points Derived Confidence Map as a Cue For Class-Agnostic Segmentation Using Deep Neural Network

1 code implementation6 Jun 2019 Shadab Khan, Ahmed H. Shahin, Javier Villafruela, Jianbing Shen, Ling Shao

To automate the process of segmenting an anatomy of interest, we can learn a model from previously annotated data.
