AI-Enabled Crater-Based Navigation for Lunar Mapping
Sofia McLeod, Chee-Kheng Chng, Matthew Rodda +1
Crater-Based Navigation (CBN) uses the ubiquitous impact craters of the Moon observed on images as natural landmarks to determine the six degrees of freedom pose of a spacecraft. T…
Direct initial orbit determination
Chee-Kheng Chng, Trent Jansen-Sturgeon, Timothy Payne +1
Initial orbit determination (IOD) is an important early step in the processing chain that makes sense of and reconciles the multiple optical observations of a resident space object…
ROSIA: Rotation-Search-Based Star Identification Algorithm
Chee-Kheng Chng, Alvaro Parra Bustos, Benjamin McCarthy +1
This paper presents a rotation-search-based approach for addressing the star identification (Star-ID) problem. The proposed algorithm, ROSIA, is a heuristics-free algorithm that se…
Monocular Rotational Odometry with Incremental Rotation Averaging and Loop Closure
Chee-Kheng Chng, Alvaro Parra, Tat-Jun Chin +1
Estimating absolute camera orientations is essential for attitude estimation tasks. An established approach is to first carry out visual odometry (VO) or visual SLAM (V-SLAM), and…
ICDAR 2019 Competition on Large-scale Street View Text with Partial Labeling -- RRC-LSVT
Yipeng Sun, Zihan Ni, Chee-Kheng Chng +9
Robust text reading from street view images provides valuable information for various applications. Performance improvement of existing methods in such a challenging scenario heavi…
ICDAR2019 Robust Reading Challenge on Arbitrary-Shaped Text (RRC-ArT)
Chee-Kheng Chng, Yuliang Liu, Yipeng Sun +11
This paper reports the ICDAR2019 Robust Reading Challenge on Arbitrary-Shaped Text (RRC-ArT) that consists of three major challenges: i) scene text detection, ii) scene text recogn…
Total-Text: A Comprehensive Dataset for Scene Text Detection and Recognition
Chee Kheng Chng, Chee Seng Chan
Text in curve orientation, despite being one of the common text orientations in real world environment, has close to zero existence in well received scene text datasets such as ICD…
