Seeing Glass: Joint Point Cloud and Depth Completion for Transparent Objects

no code implementations30 Sep 2021 Haoping Xu, Yi Ru Wang, Sagi Eppel, Alàn Aspuru-Guzik, Florian Shkurti, Animesh Garg

To address the shortcomings of existing transparent object data collection schemes in literature, we also propose an automated dataset creation workflow that consists of robot-controlled image collection and vision-based automatic annotation.

Computer vision for liquid samples in hospitals and medical labs using hierarchical image segmentation and relations prediction

1 code implementation4 May 2021 Sagi Eppel, Haoping Xu, Alan Aspuru-Guzik

This work explores the use of computer vision for image segmentation and classification of medical fluid samples in transparent containers (for example, tubes, syringes, infusion bags).

Deep Molecular Dreaming: Inverse machine learning for de-novo molecular design and interpretability with surjective representations

1 code implementation17 Dec 2020 Cynthia Shen, Mario Krenn, Sagi Eppel, Alan Aspuru-Guzik

We expect that extending PASITHEA to larger datasets, molecules and more complex properties will lead to advances in the design of new functional molecules as well as the interpretation and explanation of machine learning models.

Generator evaluator-selector net for panoptic image segmentation and splitting unfamiliar objects into parts

2 code implementations24 Aug 2019 Sagi Eppel, Alan Aspuru-Guzik

The generator/evaluator approach for this case consists of two independent convolutional neural nets: a generator net that suggests variety segments corresponding to objects, stuff and parts regions in the image, and an evaluator net that chooses the best segments to be merged into the segmentation map.

Class-independent sequential full image segmentation, using a convolutional net that finds a segment within an attention region, given a pointer pixel within this segment

1 code implementation20 Feb 2019 Sagi Eppel

The net was tested and trained on the COCO panoptic dataset and achieved 67% IOU for segmentation of familiar classes (that were part of the net training set) and 53% IOU for segmentation of unfamiliar classes (that were not included in the training).

Classifying a specific image region using convolutional nets with an ROI mask as input

2 code implementations1 Dec 2018 Sagi Eppel

This goal is achieved using a standard image classification net with the addition of a side branch, which converts the ROI mask into an attention map.

Hierarchical semantic segmentation using modular convolutional neural networks

no code implementations14 Oct 2017 Sagi Eppel

It applies one fully convolutional neural net to segment the image into vessel and background, and the vessel region is used as an input for a second net which recognizes the contents of the glass vessel.

Setting an attention region for convolutional neural networks using region selective features, for recognition of materials within glass vessels

2 code implementations29 Aug 2017 Sagi Eppel

This valve filter effectively acts as a valve that inhibits specific features in different image regions according to the ROI map.

Tracing liquid level and material boundaries in transparent vessels using the graph cut computer vision approach

1 code implementation31 Jan 2016 Sagi Eppel

The bottom 10% of the vessel region in the image is assumed to correspond to the material phase and defined as the graph and source.

Using curvature to distinguish between surface reflections and vessel contents in computer vision based recognition of materials in transparent vessels

no code implementations30 May 2015 Sagi Eppel

Reflections and the functional parts of a vessels surface can create strong edges that can be mistakenly identified as corresponding to the vessel contents, and cause recognition errors.

Tracing the boundaries of materials in transparent vessels using computer vision

no code implementations20 Jan 2015 Sagi Eppel

The probability that a curve matches the material boundary in the image is evaluated using a cost function based on some image properties along this curve.

Computer vision-based recognition of liquid surfaces and phase boundaries in transparent vessels, with emphasis on chemistry applications

no code implementations28 Apr 2014 Sagi Eppel, Tal Kachman

The method then compares each curve to the image to rate its correspondence with the outline of the real liquid surface by examining various image properties in the area surrounding each point of the curve.
