Automated separation of binary overlapping trees
First Claim
Patent Images
1. A method for image analysis, comprising:
- receiving an image comprising a plurality of overlapping tree structures;
generating a potential connectivity map (PCM) based on the plurality of overlapping tree structures, wherein the PCM comprises segments;
determining potential connectivity between the segments and a corresponding cost for each potential connectivity by artificially extending the segments until one or more of;
a respective neighbor is reached or a respective maximum extension is reached, wherein the maximum extension comprises a circular sector based on a radius proportional to a segment length measured from a head of the segment to a tail of the segment;
processing the PCM to separate the plurality of overlapping tree structures into separate tree structures with a minimal cost; and
outputting the separate tree structures having minimal cost.

Abstract
Provided are systems and methods for analyzing images. An exemplary method can comprise receiving at least one image having one or more annotations indicating a feature. The method can comprise generating training images from the at least one image. Each training image can be based on a respective section of the at least one image. The training images can comprise positive images having the feature and negative images without the feature. The method can comprise generating a feature space based on the positive images and the negative images. The method can further comprise identifying the feature in one or more unclassified images based upon the feature space.
