ABSTRACT:
A process for color graphics image processing, related to detection and segmentation of sweeps, is provided. An input graphics image is transformed into a three-dimensional histogram in an appropriate color space104(e.g., CIELUV). Two-dimensional histograms are estimated from the three-dimensional histogram106.The two-dimensional histograms are processed to detect and segment sweeps108.Sweep segment information from the processing of the two-dimensional histograms is combined110.The combined sweep segment information is used to process the input graphics image to identify and segment sweeps112.Post-processing may be optionally and selectively used to reject false alarms (i.e., areas falsely identified as sweeps)114.
