## Abstract (arXiv)

The leading segmentation methods represent the output map as a pixel grid. We study an alternative representation in which the object edges are modeled, per image patch, as a polygon with k vertices that is coupled with per-patch label probabilities. The vertices are optimized by employing a differentiable neural renderer to create a raster image. The delineated region is then compared with the ground truth segmentation. Our method obtains multiple state-of-the-art results: 76.26% mIoU on the Cityscapes validation, 90.92% IoU on the Vaihingen building segmentation benchmark, 66.82% IoU for the MoNU microscopy dataset, and 90.91% for the bird benchmark CUB. Our code for training and reproducing these results is attached as supplementary.
