Fig. 5From: Multi-class segmentation of neuronal structures in electron microscopy imagesFeature extraction process. We apply a set of filters at scales σ1,…,σn to each stack slice. a two filters for one slice, s000 left, λ3 right; b a feature of voxel Vi is the sum of the values of one box (in blue). The feature vector of Vi is the concatenation of several hundreds of such featuresBack to article page
