Noise-in, Bias-out: Balanced and Real-time MoCap Solving

no code implementations25 Sep 2023 Georgios Albanis, Nikolaos Zioulis, Spyridon Thermos, Anargyros Chatzitofis, Kostas Kolomvatsos

By relying on a unified representation, we show that training such a model is not bound to high-end MoCap training data acquisition, and exploit the advances in marker-less MoCap to acquire the necessary data.

A Low-Cost & Real-Time Motion Capture System

no code implementations CVPR 2022 Anargyros Chatzitofis, Georgios Albanis, Nikolaos Zioulis, Spyridon Thermos

Traditional marker-based motion capture requires excessive and specialized equipment, hindering accessibility and wider adoption.

On Coordinate Decoding for Keypoint Estimation Tasks

no code implementations19 Oct 2021 Anargyros Chatzitofis, Nikolaos Zioulis, Georgios Nikolaos Albanis, Dimitrios Zarpalas, Petros Daras

A series of 2D (and 3D) keypoint estimation tasks are built upon heatmap coordinate representation, i. e. a probability map that allows for learnable and spatially aware encoding and decoding of keypoint coordinates on grids, even allowing for sub-pixel coordinate accuracy.

DeepMoCap: Deep Optical Motion Capture Using Multiple Depth Sensors and Retro-Reflectors

1 code implementation14 Oct 2021 Anargyros Chatzitofis, Dimitrios Zarpalas, Stefanos Kollias, Petros Daras

DeepMoCap explores motion capture by automatically localizing and labeling reflectors on depth images and, subsequently, on 3D space.

Self-Supervised Deep Depth Denoising

1 code implementation ICCV 2019 Vladimiros Sterzentsenko, Leonidas Saroglou, Anargyros Chatzitofis, Spyridon Thermos, Nikolaos Zioulis, Alexandros Doumanoglou, Dimitrios Zarpalas, Petros Daras

Specifically, the proposed autoencoder exploits multiple views of the same scene from different points of view in order to learn to suppress noise in a self-supervised end-to-end manner using depth and color information during training, yet only depth during inference.
