Abstract:
My research has been motivated by the problem of segmenting 3d electron 
microscopy images of brain tissue in order to reconstruct neural 
circuits. Such images require instance level segmentation (we want to 
label each individual neuron separately) and are extremely cluttered 
(the image is densely filled with cells). The gap between human and 
machine performance on this task seems to lie in the ability of humans 
to focus on individual objects and make use of priors on their shapes.

State of the art techniques for this problem rely on supervised deep 
neural networks to perform boundary detection. I will present an 
approach to augmenting such networks with an attentional mechanism with 
the goal of forcing the network to focus on a single object at a time, 
thereby allowing better use of priors on the shapes of individual objects.
