Unsupervised Iterative U-Net with an Internal Guidance Layer for Vertebrae Contrast Enhancement in Chest X-Ray Images

no code implementations6 Jun 2023 Ella Eidlin, Assaf Hoogi, Nathan S. Netanyahu

This innovative approach has the potential to significantly enhance the diagnostic accuracy and early detection of diseases, making it a promising advancement in X-ray imaging technology.

Improving Gradient-Trend Identification: Fast-Adaptive Moment Estimation with Finance-Inspired Triple Exponential Moving Average

no code implementations2 Jun 2023 Roi Peleg, Teddy Lazebnik, Assaf Hoogi

Existing optimizers predominantly adopt techniques based on the first-order exponential moving average (EMA), which results in noticeable delays that impede the real-time tracking of gradients trend and consequently yield sub-optimal performance.

Deep Active Lesion Segmentation

1 code implementation19 Aug 2019 Ali Hatamizadeh, Assaf Hoogi, Debleena Sengupta, Wuyue Lu, Brian Wilcox, Daniel Rubin, Demetri Terzopoulos

Lesion segmentation is an important problem in computer-assisted diagnosis that remains challenging due to the prevalence of low contrast, irregular boundaries that are unamenable to shape priors.

From voxels to pixels and back: Self-supervision in natural-image reconstruction from fMRI

2 code implementations NeurIPS 2019 Roman Beliy, Guy Gaziv, Assaf Hoogi, Francesca Strappini, Tal Golan, Michal Irani

Unfortunately, acquiring sufficient "labeled" pairs of {Image, fMRI} (i. e., images with their corresponding fMRI responses) to span the huge space of natural images is prohibitive for many reasons.

Self-Attention Capsule Networks for Object Classification

no code implementations29 Apr 2019 Assaf Hoogi, Brian Wilcox, Yachee Gupta, Daniel L. Rubin

Then, the Self-Attention layer learns to suppress irrelevant regions based on features analysis and highlights salient features useful for a specific task.

TVAE: Triplet-Based Variational Autoencoder using Metric Learning

2 code implementations13 Feb 2018 Haque Ishfaq, Assaf Hoogi, Daniel Rubin

Deep metric learning has been demonstrated to be highly effective in learning semantic representation and encoding information that can be used to measure data similarity, by relying on the embedding learned from metric learning.

A Fully-Automated Pipeline for Detection and Segmentation of Liver Lesions and Pathological Lymph Nodes

no code implementations19 Mar 2017 Assaf Hoogi, John W. Lambert, Yefeng Zheng, Dorin Comaniciu, Daniel L. Rubin

We propose a fully-automated method for accurate and robust detection and segmentation of potentially cancerous lesions found in the liver and in lymph nodes.

Adaptive Local Window for Level Set Segmentation of CT and MRI Liver Lesions

no code implementations12 Jun 2016 Assaf Hoogi, Christopher F. Beaulieu, Guilherme M. Cunha, Elhamy Heba, Claude B. Sirlin, Sandy Napel, Daniel L. Rubin

We compare our method to a global level set segmentation and to local framework that uses predefined fixed-size square windows.
