CoHelix: Event-Based Multi-Propeller Rotation-Rate Tracking with Shared Projective Geometry
Radim Spetlik, Tobiáš Vinklárek, Jan Klivan +3
Estimating propeller rates from a moving event camera requires separating blade rotation from the changing image geometry. Background activity mixes with blade events, while repeat…
Unwarping the Lens: A Physics-Grounded Approach to Video Glasses Removal
Radim Spetlik, David Futschik, Radek Danecek +4
High-fidelity removal of eyeglasses from video is a major challenge in facial attribute editing, as the underlying facial geometry is often obscured by complex refractive distortio…
Relative State Estimation using Event-Based Propeller Sensing
Ravi Kumar Thakur, Luis Granados Segura, Jan Klivan +4
Autonomous swarms of multi-Unmanned Aerial Vehicle (UAV) system requires an accurate and fast relative state estimation. Although monocular frame-based camera methods perform well…
HelixTrack: Event-Based Tracking and RPM Estimation of Propeller-like Objects
Radim Spetlik, Michal Pliska, Vojtěch Vrba +1
Safety-critical perception for unmanned aerial vehicles and rotating machinery requires microsecond-latency tracking of fast, periodic motion under egomotion and strong distractors…
StructuReiser: A Structure-preserving Video Stylization Method
Radim Spetlik, David Futschik, Daniel Sykora
We introduce StructuReiser, a novel video-to-video translation method that transforms input videos into stylized sequences using a set of user-provided keyframes. Unlike existing a…
EEPPR: Event-based Estimation of Periodic Phenomena Rate using Correlation in 3D
Jakub Kolář, Radim Špetlík, Jiří Matas
We present a novel method for measuring the rate of periodic phenomena (e.g., rotation, flicker, and vibration), by an event camera, a device asynchronously reporting brightness ch…
EE3P: Event-based Estimation of Periodic Phenomena Properties
Jakub Kolář, Radim Špetlík, Jiří Matas
We introduce a novel method for measuring properties of periodic phenomena with an event camera, a device asynchronously reporting brightness changes at independently operating pix…
