Abstract
A system and method of processing segmentation tags is disclosed. In accordance with the present invention, a method for processing segmentation tags that receives blocks of segmentation tags each of which has an associated block level tag that is representative of the segmentation tags within the block. The method positions a neighborhood window about a current block and a neighboring block and cleans a target segmentation tag within the current block based upon the block level tags within the neighborhood window using a set of tag cleaning rules.
Claims14
A method of processing segmentation tags, comprising:
- identifying a current pixel level tag;
- identifying a neighborhood window comprising a plurality of segmentation tags;
- and
- cleaning the current pixel level tag based upon the segmentation tags within the neighborhood window.
A method for processing segmentation tags, comprising:
- receiving blocks of segmentation tags, each of the received blocks having an associated block level tag representative of the segmentation tags within the block;
- positioning a neighborhood window about a current block and a neighboring block;
- and
- cleaning a target segmentation tag within the current block based upon the block level tags within the neighborhood window.
A system for processing video image data, comprising:
- a print engine connected to receive print ready data, the marking engine generating an image on a receiving medium in response to the print ready data;
- and
- a image processor connected to receive video image data, the image processor generating the print ready data from the video image data, the image processor comprising
- a segmentation processor coupled to receive the video image data, the segmentation processor generating segmentation tags that identify image pixels as a particular image class;
- a neighborhood window generator connected to receive said segmentation tags, the neighborhood window generator identifying a neighborhood window comprising blocks of segmentation tags, each block having an associated block tag;
- and
- a tag analysis module connected to receive the blocks of segmentation tags and the associated block tags, the tag analysis module replacing selected segmentation tags within the blocks with a cleaned tag.
