Abstract:
A method for erasing a feature from a digital image, comprising:identifying a plurality of tip regions on the image each including multiple pixels of the image and each covering a portion of the feature; and sequentially processing the tip regions to erase the feature including determining an erasure color, defining a color match function for the tip region, applying the color match function to each pixel in the tip region including determining a color match value for each pixel, completely erasing ones of the pixels in the tip region that have a color match value greater than a threshold value, and for a pixel having a color match value less than the threshold, applying an erasure function to the target pixel and removing a contribution of the erasure color from a color associated with the target pixel where the effect of each action of processing a tip region is recorded in the digital image before any subsequent action of processing a tip region is performed.
