Localisation of Drosophila embryos using active contours in channel spaces

In this paper, we introduce an active contour based scheme to localise Drosophila embryos in RGB images. An active contour (initiated as a closed one) maybe converge to an open contour, e.g., in the case that a targeting embryo is touched by a neighbouring one. We propose an algorithmic strategy to detect and restore open active contours. The experiment results show the promise of the proposed scheme.
