Topological Sweep for Multi-Target Detection of Geostationary Space Objects

We propose an algorithm to detect Geostationary space objects using topological sweep.

Local contrast as an effective means to robust clustering against varying densities

Most density-based clustering methods have difficulties detecting clusters of hugely different densities in a dataset. A recent density-based clustering CFSFDP appears to have mitigated the issue. However, through formalising the condition under …

Half-space mass: a maximally robust and efficient data depth method

Data depth is a statistical method which models data distribution in terms of center-outward ranking rather than density or linear ranking. While there are a lot of academic interests, its applications are hampered by the lack of a method which is …
