In this paper, an unsupervised color image segmentation scheme is proposed using homotopy continuation method. Different variants of MRF model is used to preserve both strong and weak edges. A Compound Markov Random Field (COMRF) model with Bi-level Binary Line Fields is proposed. The scheme is specifically meant to preserve weak edges besides the well defined strong edges.The proposed scheme i...

Some species in the dinoflagellate genus Alexandrium spp. produce a suite of neurotoxins that block sodium channels, known as paralytic shellfish toxins (PST), which have deleterious effects on grazers. Populations of the ubiquitous copepod grazer Acartia hudsonica that have co-occurred with toxic Alexandrium spp. are better adapted than naïve populations. The mechanism of adaptation is current...

Copepods are among the most abundant and diverse groups of mesozooplankton in the world's oceans. Each species has a certain depth range within which different individuals (of the same life stage and sex) are found. Lipids are accumulated in many calanoid copepods for energy storage and reproduction. Lipid content in some species increases with depth, however studies so far focused mostly on te...
