<p><P>PROBLEM TO BE SOLVED: To partially detect and construct transparent overlapping graphical objects from a single image. <P>SOLUTION: A method (500), apparatus and computer-readable storage medium for generating an object representation from a bitmap image are disclosed. A set of regions including a background region is selected from the bitmap image (510). Color and partial transparency parameters of a first graphical object with partial transparency that overlaps a second graphical object are estimated according to colors of the set of regions (520). The estimated color and partial transparency are consistent with a transparency composition model. Geometric models of the first and second graphical objects are constructed from the set of regions and the estimated color and transparency parameters of the first graphical object (530). The object representation is generated dependent upon the geometric models (540). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
