Abstract:We propose a novel snake initialization as well as validation technique to automate snake/active contour for multiple objects detection. We apply a probabilistic quad tree based approximate segmentation to find the regions of interest (ROI) in an image, evolve snakes within ROIs and finally classify the snakes into object and non-object classes using boosting. We propose a novel loss function for boosting that is more robust to outliers and we derive a modified Adaboost algorithm by minimizing the proposed los… Show more
“…The contour might contain an object if its reconstruction error is less than a given threshold. Reference [9] does not sow randomly in the image's global area, and determines the area in which the objects probably exist at first. Second, the seed points are sowed in the area.…”

“…In the second phase, segmentation of multiple objects in the image is executed by GVF. In [8][9], a seed point corresponds to one object, and this is the initial contour at the start of evolution. Then these seed points evolve into contours that contain objects under the expansion strategy.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
