Multi-view Image-based Hand Geometry Refinement using Differentiable Monte Carlo Ray Tracing

no code implementations12 Jul 2021 Giorgos Karvounas, Nikolaos Kyriazis, Iason Oikonomidis, Aggeliki Tsoli, Antonis A. Argyros

The amount and quality of datasets and tools available in the research field of hand pose and shape estimation act as evidence to the significant progress that has been made. However, even the datasets of the highest quality, reported to date, have shortcomings in annotation.

Even Faster SNN Simulation with Lazy+Event-driven Plasticity and Shared Atomics

1 code implementation8 Jul 2021 Dennis Bautembach, Iason Oikonomidis, Antonis Argyros

It offers higher bandwidth than event-driven plasticity alone and achieves a 1. 5x-2x speedup over our closest competitor.

H-GAN: the power of GANs in your Hands

1 code implementation27 Mar 2021 Sergiu Oprea, Giorgos Karvounas, Pablo Martinez-Gonzalez, Nikolaos Kyriazis, Sergio Orts-Escolano, Iason Oikonomidis, Alberto Garcia-Garcia, Aggeliki Tsoli, Jose Garcia-Rodriguez, Antonis Argyros

Relying on image-to-image translation, we improve the appearance of synthetic hands to approximate the statistical distribution underlying a collection of real images of hands.

Image-to-Image Translation Tone Mapping +1

Multi-GPU SNN Simulation with Static Load Balancing

no code implementations9 Feb 2021 Dennis Bautembach, Iason Oikonomidis, Antonis Argyros

We present a SNN simulator which scales to millions of neurons, billions of synapses, and 8 GPUs.

Faster and Simpler SNN Simulation with Work Queues

1 code implementation16 Dec 2019 Dennis Bautembach, Iason Oikonomidis, Nikolaos Kyriazis, Antonis Argyros

We present a clock-driven Spiking Neural Network simulator which is up to 3x faster than the state of the art while, at the same time, being more general and requiring less programming effort on both the user's and maintainer's side.

ReActNet: Temporal Localization of Repetitive Activities in Real-World Videos

no code implementations14 Oct 2019 Giorgos Karvounas, Iason Oikonomidis, Antonis Argyros

On top of this representation, we design, implement and evaluate ReActNet, a lightweight convolutional neural network that classifies a given frame as belonging (or not) to a repetitive video segment.

Using a single RGB frame for real time 3D hand pose estimation in the wild

no code implementations11 Dec 2017 Paschalis Panteleris, Iason Oikonomidis, Antonis Argyros

We present a method for the real-time estimation of the full 3D pose of one or more human hands using a single commodity RGB camera.

3D Hand Pose Estimation Camera Calibration

Evolutionary Quasi-random Search for Hand Articulations Tracking

no code implementations CVPR 2014 Iason Oikonomidis, Manolis I.A. Lourakis, Antonis A. Argyros

The method has been tested for the problems of tracking the articulation of a single hand (27D parameter space) and two hands (54D space).
