HotSpotDetection

HotSpotDetection software

Overview

The HotSpotDetection software written in C++ enables to detect fluorescence accumulation over time in video-microscopy. The cumulated detection maps enable to extract more reliably the regions of interest. In practice, this method only requires the setting of the false alarm probability.

We adopt a MRF framework to capture image regularity. In contrast to the usual pixel-wise MRF models, a recent line of work consists in modeling non-local interactions from image patches. The redundancy property and patch-based representation is here exploited to detect unusual spatial patterns seen in the scene. This property holds true in fluorescence imaging and we propose a patch-based Gibbs/MRF modeling to represent the more regular image components. Furthermore, we detect the locations where redundancy is low, that is protein concentrations against a nearly uniform background ideally.
