Improved repeatability measures for evaluating performance of feature detectors
Shoaib Ehsan, Nadia Kanwal, Adrian F. Clark +1
The most frequently employed measure for performance characterisation of local feature detectors is repeatability, but it has been observed that this does not necessarily mirror ac…
Hardware based Scale- and Rotation-Invariant Feature Extraction: A Retrospective Analysis and Future Directions
Shoaib Ehsan, Adrian F. Clark, Klaus D. McDonald-Maier
Computer Vision techniques represent a class of algorithms that are highly computation and data intensive in nature. Generally, performance of these algorithms in terms of executio…
Exploring Integral Image Word Length Reduction Techniques for SURF Detector
Shoaib Ehsan, Klaus D. McDonald-Maier
Speeded Up Robust Features (SURF) is a state of the art computer vision algorithm that relies on integral image representation for performing fast detection and description of imag…
On-Board Vision Processing For Small UAVs: Time to Rethink Strategy
Shoaib Ehsan, Klaus D. McDonald-Maier
The ultimate research goal for unmanned aerial vehicles (UAVs) is to facilitate autonomy of operation. Research in the last decade has highlighted the potential of vision sensing i…
