Structure-guided image processing and image feature enhancement

摘要

A structure guided image processing system uses geometric structure information to guide image feature extraction and enhancement of an input image to produce a weight image output and a mask image output. Geometric structure information may be apparent in the nature of the images, or it can in many cases be derived from CAD information. Idempotent processing and filtering operations minimize image distortion. Directional elongated structuring elements provide structure-guided selective processing and high speed filtering throughput.
