pair of vertices by analyzing the graphical image. The contour is detected by
computing the shortest path between vertices based upon weights generated by
the gradient of the underlying image.
Representative claim 1 is reproduced as follows:
A system for processing boundary information of a graphical object,
comprising:
code for receiving a graphical image that comprises said graphical object ,
[sic]
wherein said graphical object is defined by at Ieast said boundary
information;
code for detecting a plurality of contours between respective pairs of
points of said graphical image, wherein individual ones of the contours are
detected responsive to respective user input of a user; and
code for determining a plurality of vertices from said boundary
information, wherein respective contours, which are between adjacent vertices of
said plurality of vertices and are detected by said code for detecting, approximate
respective edges of said boundary information within a distortion criterion.
