Digital image processing method and system for the extraction of digital objects

摘要

The location of an object is in four steps. The image is segmented into homogeneous regions (Rp(S)), which are labelled as one of: not labelled, significant, or non-significant. Neighboring significant regions are fused into zones (Z1 - Z4), and boxes (B1-B4) enclosing zones determined. An intercept vector is used to construct the object contour, which is refined by filtering.
