Abstract
The method for determining property feature segmentation includes: receiving a region image for a region; determining parcel data for the region; determining a final segmentation output based on the region image and parcel data using a trained segmentation module; optionally generating training data; and training a segmentation module using the training data S500.
Claims21
A method, comprising:
- receiving a region image that depicts a property feature;
- determining an instance-aware mask for the property feature and a semantic segmentation mask for the property feature, based on the region image;
- computing a distance transform from the instance-aware mask;
- determining a flooded mask by assigning instance identifiers to pixels of the instance-aware mask based on the distance transform;
- and
- generating a pixel-accurate mask by combining the flooded mask and the semantic segmentation mask.

A method for generating training data for property feature segmentation, comprising:
- receiving a region image of a property feature;
- receiving multiple property feature segment polygon sets for the region image;
- retrieving parcel data for a region depicted in the region image;
- generating an instance polygon set by combining contiguous property feature segment polygons of a property feature segment polygon set that are within a common parcel, where in the common parcel is determined based on the parcel data;
- and
- generating a label for the region image by combining the instance polygon sets;
- wherein the region image and the label are used to train a segmentation module.
