From Top-Right to User-Right: Perceptual Prioritization of Point-Feature Label Positions
Petr Bobák, Ladislav Čmolík, Martin Čadík
In cartography, Geographic Information Systems (GIS), and visualization, the position of a label relative to its point feature is crucial for readability and user experience. Along…
Estimating Extreme 3D Image Rotation with Transformer Cross-Attention
Shay Dekel, Yosi Keller, Martin Cadik
The estimation of large and extreme image rotation plays a key role in multiple computer vision domains, where the rotated images are related by a limited or a non-overlapping fiel…
Reinforced Labels: Multi-Agent Deep Reinforcement Learning for Point-Feature Label Placement
Petr Bobák, Ladislav Čmolík, Martin Čadík
Over the recent years, Reinforcement Learning combined with Deep Learning techniques has successfully proven to solve complex problems in various domains, including robotics, self-…
Resource Efficient Mountainous Skyline Extraction using Shallow Learning
Touqeer Ahmad, Ebrahim Emami, Martin Čadík +1
Skyline plays a pivotal role in mountainous visual geo-localization and localization/navigation of planetary rovers/UAVs and virtual/augmented reality applications. We present a no…
PTRM: Perceived Terrain Realism Metrics
Suren Deepak Rajasekaran, Hao Kang, Bedrich Benes +5
Terrains are visually important and commonly used in computer graphics. While many algorithms for their generation exist, it is difficult to assess the realism of a generated terra…
Comparison of Semantic Segmentation Approaches for Horizon/Sky Line Detection
Touqeer Ahmad, Pavel Campr, Martin Čadík +1
Horizon or skyline detection plays a vital role towards mountainous visual geo-localization, however most of the recently proposed visual geo-localization approaches rely on \textb…
Camera Pose Estimation from Lines using Plücker Coordinates
Bronislav Přibyl, Pavel Zemčík, Martin Čadík
Correspondences between 3D lines and their 2D images captured by a camera are often used to determine position and orientation of the camera in space. In this work, we propose a no…
Absolute Pose Estimation from Line Correspondences using Direct Linear Transformation
Bronislav Přibyl, Pavel Zemčík, Martin Čadík
This work is concerned with camera pose estimation from correspondences of 3D/2D lines, i. e. with the Perspective-n-Line (PnL) problem. We focus on large line sets, which can be e…
Camera Elevation Estimation from a Single Mountain Landscape Photograph
Martin Cadik, Jan Vasicek, Michal Hradis +2
This work addresses the problem of camera elevation estimation from a single photograph in an outdoor environment. We introduce a new benchmark dataset of one-hundred thousand imag…
