SYSTEM AND METHOD TO ENABLE CORRECTION TO APPLICATION OF SUBSTANTIALLY COLORLESS MATERIAL OVER IDENTIFIED TEXT VIA SEGMENTATION
First Claim
1. A processor-implemented method for processing image data in an image processing apparatus, the image processing apparatus comprising at least one processor for processing documents containing image data comprising a plurality of pixels, the method comprising the following acts implemented by the at least one processor:
- receiving a page description language file of image data comprising a plurality of pixels and related image instructions;
raster image processing the page description language file to create a bitmap file with a first data structure indicating at least pixels representing text;
segmenting the bitmap file to determine at least pixels in the bitmap file representing text not indicated in the first data structure to form a second data structure, andcombining the first data structure and the second data structure to form a third data structure indicating locations for marking substantially colorless marking material onto a substrate using an image output device.

Abstract
Disclosed is a processor-implemented method for processing image data using an image processing apparatus. The processor is configured to receive a PDL file of image data and raster image process (RIP) the PDL file to determine pixels representing text. The ripped file is then segmented to determine at least any pixels representing text that were not initially indicated or identified by the ripped file. The results are combined to determine locations for marking onto a substrate by the output device using substantially colorless marking material over text pixels (to coat marked text pixels). In some instances, locations for covering text pixels with substantially colorless marking material can be tagged during segmenting image data, using a tag plane.
