AUTOMATIC AND SEMI-AUTOMATIC DETECTION OF PLANAR SHAPES FROM 2D IMAGES

摘要

A method is disclosed to digitize and recognize planar shapes that are present in images and are desired to be recognized and extracted. These planar shapes can represent maps in cartography, they can represent patterns from garment styles, they can represent projections of real objects into a 2D picture. The images are obtained from image scanning techniques including digital cameras. The invention includes an automatic mode and a user interface for the semi-automatic mode of operation. The method has been carried out for patterns that were drawn or plotted on papers (not cut out), representing garment styles, and is readily applicable to other applications such as maps in cartography, and more generally to recognition of 3D objects from 2D images. It could be use d as a module for any image processing software.
