Exploring Easy Boosts for Lidar Semantic Scene Completion

Tetiana Martyniuk, Jonathan Seele, Alexandre Boulch, Gilles Puy, Renaud Marlet, Raoul de Charette
IEEE ICIP 2026

This paper, a.k.a. SSC-Priors, is a study of plug-and-play semantic and visibility input priors that boost four lidar SSC baselines by +5.2 mIoU on average on SemanticKITTI. With no architectural redesign beyond the first layer needed, we reach SOTA in mIoU among reproducible single-frame methods.

LiDPM: Rethinking Point Diffusion for Lidar Scene Completion

Tetiana Martyniuk, Gilles Puy, Alexandre Boulch, Renaud Marlet, Raoul de Charette
IEEE IV 2025 (Oral Presentation)

LiDPM is a diffusion model for scene-level lidar completion that leverages a vanilla DDPM avoiding the need for local diffusion approximations.

FEAR: Fast, Efficient, Accurate and Robust Visual Tracker

Vasyl Borsuk, Roman Vei, Orest Kupyn Tetiana Martyniuk, Igor Krashenyi, Jiří Matas
ECCV 2022

FEAR is a family of Siamese visual trackers that combine dual-template adaptation, pixel-wise fusion, and efficient backbones to achieve state-of-the-art accuracy and speed, while also introducing a new benchmark for evaluating energy-efficient tracking.

DAD-3DHeads: A Large-scale Dense, Accurate and Diverse Dataset for 3D Head Alignment from a Single Image

Tetiana Martyniuk*, Orest Kupyn*, Yana Kurlyak, Igor Krashenyi, Jiři Matas, Viktoriia Sharmanska
CVPR 2022

DAD-3DHeads is a large-scale, diverse dataset with over 3.5K 3D head landmarks, and DAD-3DNet is a robust model trained on it for dense 3D head alignment, achieving state-of-the-art results in pose, shape reconstruction, and landmark estimation across multiple benchmarks.

DeblurGAN-v2: Deblurring (Orders-of-Magnitude) Faster and Better

Orest Kupyn, Tetiana Martyniuk, Junru Wu, Zhangyang Wang
ICCV 2019

DeblurGAN-v2 is an end-to-end GAN for single image motion deblurring that combines a relativistic conditional GAN, double-scale discriminator, and Feature Pyramid Network to deliver state-of-the-art quality and efficiency across various backbones, enabling real-time performance and broader applicability to image restoration.

Journal Papers

Kuratowski Monoids of n-Topological Spaces

Taras Banakh, Ostap Chervak, Tetyana Martynyuk, Maksym Pylypovych, Alex Ravsky, Markiyan Simkiv
Topological Algebra and its Applications, Volume 6 Issue 1, 2018

The main result of this paper generalizes the famous Kuratowski 14-set closure-complement Theorem to polytopological spaces.

Patents

Information compression method and apparatus

Vladyslav Zavadskyi, Tetiana Martyniuk
United States Patent, US12198391B2, Jan. 14, 2025

This method introduces a control circuit and neural network pipeline that compresses 3D source field information into compact vector representations over subdivided spaces, enabling efficient field value estimation via a trained encoder-decoder model.

Preprints

A Controlled Hahn-Mazurkiewicz Theorem and its Applications

Taras Banakh, Tetiana Martyniuk, Magdalena Nowak, Filip Strobin
arXiv preprint, 2023

This paper contains the proof of the controlled version of the classical Hahn-Mazurkiewicz Theorem that provides upper and lower bound of the Hölder dimension of a metric Peano continuum as a function of its S-dimension.
