Using our method, we achieved a mean error-free neurite path length of 1.1 mm, and we observed only four mergers in a test set with a path length of 97 mm. We used flood-filling networks to trace neurons in a dataset obtained by serial block-face electron microscopy of a zebra finch brain. We present flood-filling networks, a method for automated segmentation that, similar to most previous efforts, uses convolutional neural networks, but contains in addition a recurrent pathway that allows the iterative optimization and extension of individual neuronal processes. Automated approaches have been developed for tracing, but their error rates are too high to generate reliable circuit diagrams without extensive human proofreading. Reconstruction of neural circuits from volume electron microscopy data requires the tracing of cells in their entirety, including all their neurites. The resulting model is fast to compute, converges more rapidly and requires fewer examples to achieve a given performance than more general techniques such as U-Net. A simple model containing a sequence of five such blocks was tested on CHASE-DB1 dataset, and achieved better performance comparing to the benchmark with only \(0.6\%\) of the parameters and \(25\%\) of the training examples. Invariance to scale can be added using a pyramid pooling layer. We use Gabor functions to guide the training of the kernels, and demonstrate that the resulting kernels generally form rotated versions of the same pattern. This introduces a degree of orientation invariance by construction. We show how two basis kernels can lead to the equivalent of eight orientations. In particular, by reflecting and rotating a single oriented kernel we can generate four versions at different angles. We introduce the Multi Angle and Scale Convolutional Unit (MASC) with a novel training approach called Response Shaping. We take advantage of this self-similarity by demonstrating a CNN based segmentation system that requires far fewer parameters than conventional approaches. Such structures often have no preferred direction and a range of possible scales.
