Building and enforcing shape priors for segmentation of alloy micrographs

Computer simulation of metal alloys is an emerging trend in materials development. Simulated replicas of fabricated alloys are based on the segmentations of alloy micrographs. Therefore, accurate segmentation of visible precipitates is paramount to simulation accuracy. Since the shape and size of precipitates are key indicators of physical alloy properties, automated segmentation algorithms must account for abundant prior information of precipitate shape. We present a new method for constructing a prior enforcing rectangular shape which can be applied within a min-cut framework for maximum a-posteriori segmentation.
