ABSTRACT:
Image objects within two-dimensional images are identified by locating boundary points that describe line segments that define a polygon outlining each object. Processing follows lines of pixels between boundary points to determine whether additional pixels are a part of the same image object by reference to a discriminator, such as color. Boundary points are thus identified for contiguous pixels and contiguous lines. Arm-like regions are identified by recursive analysis in a similar manner. The resulting boundary point list may serve to identify the image object, such as for labeling or tagging in web-based manuals, catalogs, and so forth.
