Boundary detection in serial section EM images is done by a variety of algorithms. Many algorithms were compared in the ISBI’12 2D EM segmentation challenge, a publicly available dataset and benchmark. The winning submission was an ensemble of max-pooling convolutional networks (ConvNets) created by IDSIA. In saliency detection, background priors, which are often regarded as pseudo-background, are effective clues to find salient objects in images. Although image boundary is commonly used as background priors, it does not work well for images of complex scenes and videos.
