Single-shot self-supervised particle tracking

no code implementations28 Feb 2022 Benjamin Midtvedt, Jesús Pineda, Fredrik Skärberg, Erik Olsén, Harshith Bachimanchi, Emelie Wesén, Elin K. Esbjörner, Erik Selander, Fredrik Höök, Daniel Midtvedt, Giovanni Volpe

Here, we propose a novel deep-learning method, named LodeSTAR (Low-shot deep Symmetric Tracking And Regression), that learns to tracks objects with sub-pixel accuracy from a single unlabeled experimental image.

Neural Network Training with Highly Incomplete Datasets

1 code implementation1 Jul 2021 Yu-Wei Chang, Laura Natali, Oveis Jamialahmadi, Stefano Romeo, Joana B. Pereira, Giovanni Volpe

Since the data to train the neural networks need to be complete, most studies discard the incomplete datapoints, which reduces the size of the training data, or impute the missing features, which can lead to artefacts.

Quantitative Digital Microscopy with Deep Learning

1 code implementation16 Oct 2020 Benjamin Midtvedt, Saga Helgadottir, Aykut Argun, Jesús Pineda, Daniel Midtvedt, Giovanni Volpe

We use it to exemplify how deep learning can be employed for a broad range of applications, from particle localization, tracking and characterization to cell counting and classification.

Digital video microscopy enhanced by deep learning

1 code implementation6 Dec 2018 Saga Helgadottir, Aykut Argun, Giovanni Volpe

We show that DeepTrack outperforms algorithmic approaches, especially in the presence of noise and under poor illumination conditions.

Intracavity Optical Trapping

no code implementations23 Aug 2018 Fatemeh Kalantarifard, Parviz Elahi, Ghaith Makey, Onofrio M. Maragò, F. Ömer Ilday, Giovanni Volpe

Standard optical tweezers rely on optical forces that arise when a focused laser beam interacts with a microscopic particle: scattering forces, which push the particle along the beam direction, and gradient forces, which attract it towards the high-intensity focal spot.
