Light-weight spatio-temporal graphs for segmentation and ejection fraction prediction in cardiac ultrasound

1 code implementation6 Jul 2022 Sarina Thomas, Andrew Gilbert, Guy Ben-Yosef

In particular, segmentations of the left ventricle can be used to derive ventricular volume, ejection fraction (EF) and other relevant measurements.

Semantic Segmentation

A model for full local image interpretation

no code implementations17 Oct 2021 Guy Ben-Yosef, Liav Assif, Daniel Harari, Shimon Ullman

We describe a computational model of humans' ability to provide a detailed interpretation of components in a scene.

Parallel mesh reconstruction streams for pose estimation of interacting hands

no code implementations25 Apr 2021 Uri Wollner, Guy Ben-Yosef

We present a new multi-stream 3D mesh reconstruction network (MSMR-Net) for hand pose estimation from a single RGB image.

What can human minimal videos tell us about dynamic recognition models?

1 code implementation19 Apr 2021 Guy Ben-Yosef, Gabriel Kreiman, Shimon Ullman

In human vision objects and their parts can be visually recognized from purely spatial or purely temporal information but the mechanisms integrating space and time are poorly understood.

Minimal Images in Deep Neural Networks: Fragile Object Recognition in Natural Images

no code implementations ICLR 2019 Sanjana Srivastava, Guy Ben-Yosef, Xavier Boix

Ullman et al. 2016 show that a slight modification of the location and size of the visible region of the minimal image produces a sharp drop in human recognition accuracy.

Object Recognition

Complex Relations in a Deep Structured Prediction Model for Fine Image Segmentation

no code implementations24 May 2018 Cristina Mata, Guy Ben-Yosef, Boris Katz

Many deep learning architectures for semantic segmentation involve a Fully Convolutional Neural Network (FCN) followed by a Conditional Random Field (CRF) to carry out inference over an image.

Semantic Segmentation Structured Prediction

A model for interpreting social interactions in local image regions

no code implementations26 Dec 2017 Guy Ben-Yosef, Alon Yachin, Shimon Ullman

Understanding social interactions (such as 'hug' or 'fight') is a basic and important capacity of the human visual system, but a challenging and still open problem for modeling.

Structured learning and detailed interpretation of minimal object images

no code implementations29 Nov 2017 Guy Ben-Yosef, Liav Assif, Shimon Ullman

We model the process of human full interpretation of object images, namely the ability to identify and localize all semantic features and parts that are recognized by human observers.
