Abstract
A system for semi-automated feature extraction comprising an image analysis server that receives and initializes a plurality of raster images, a feature extraction server that identifies and extracts image features, a mosaic server that assembles mosaics from multiple images, and a rendering engine that provides visual representations of images for review by a human user, and a method for generating a cost raster utilizing the system of the invention.
Claims (6)
1. A method for creating seamlines in orthomosaic imagery using a cost, comprising the steps of:
receiving, at an image analysis server, a plurality of input images;
identifying, using a feature extraction server, a plurality of linear image features within the plurality of input images;
computing a cost raster based at least in part on at least a portion of the plurality of image features identified, wherein costs are dependent at least in part on presence of similar linear features in two or more input images;
automatically generating seamlines along at least some of the linear image features using cost minimization; and
vectorizing the generated seamlines.
