Shi-NeSS: Detecting Good and Stable Keypoints with a Neural Stability Score

1 code implementation3 Jul 2023 Konstantin Pakulev, Alexander Vakhitov, Gonzalo Ferrer

Learning a feature point detector presents a challenge both due to the ambiguity of the definition of a keypoint and correspondingly the need for a specially prepared ground truth labels for such points.

SeMLaPS: Real-time Semantic Mapping with Latent Prior Networks and Quasi-Planar Segmentation

no code implementations28 Jun 2023 Jingwen Wang, Juan Tarrio, Lourdes Agapito, Pablo F. Alcantarilla, Alexander Vakhitov

We present a new methodology for real-time semantic mapping from RGB-D sequences that combines a 2D neural network and a 3D network based on a SLAM system with 3D occupancy mapping.

NeSS-ST: Detecting Good and Stable Keypoints with a Neural Stability Score and the Shi-Tomasi detector

1 code implementation ICCV 2023 Konstantin Pakulev, Alexander Vakhitov, Gonzalo Ferrer

Learning a feature point detector presents a challenge both due to the ambiguity of the definition of a keypoint and, correspondingly, the need for specially prepared ground truth labels for such points.

Uncertainty-Aware Camera Pose Estimation from Points and Lines

no code implementations CVPR 2021 Alexander Vakhitov, Luis Ferraz Colomina, Antonio Agudo, Francesc Moreno-Noguer

The new PnP(L) methods outperform the state-of-the-art on real data in isolation, showing an increase in mean translation accuracy by 18% on a representative subset of KITTI, while the new uncertain refinement improves pose accuracy for most of the solvers, e. g. decreasing mean translation error for the EPnP by 16% compared to the standard refinement on the same dataset.

StylePeople: A Generative Model of Fullbody Human Avatars

1 code implementation CVPR 2021 Artur Grigorev, Karim Iskakov, Anastasia Ianina, Renat Bashirov, Ilya Zakharkin, Alexander Vakhitov, Victor Lempitsky

We show that with the help of neural textures, such avatars can successfully model clothing and hair, which usually poses a problem for mesh-based approaches.

Real-time RGBD-based Extended Body Pose Estimation

1 code implementation5 Mar 2021 Renat Bashirov, Anastasia Ianina, Karim Iskakov, Yevgeniy Kononenko, Valeriya Strizhkova, Victor Lempitsky, Alexander Vakhitov

We use parametric 3D deformable human mesh model (SMPL-X) as a representation and focus on the real-time estimation of parameters for the body pose, hands pose and facial expression from Kinect Azure RGB-D camera.

Coordinate-based Texture Inpainting for Pose-Guided Image Generation

1 code implementation28 Nov 2018 Artur Grigorev, Artem Sevastopolsky, Alexander Vakhitov, Victor Lempitsky

Since the input photograph always observes only a part of the surface, we suggest a new inpainting method that completes the texture of the human body.
