Abstract
A system and method for method of cleaning segmentation tags is disclosed. A method in accordance with the present invention comprises receiving a plurality of segmentation tags; generating block level tags in response to the received segmentation tags wherein each block level tag is a representative tag for a block of received segmentation tags; and cleaning selected ones of the received segmentation tags using a window of neighboring block level tags.
Claims23
A method of cleaning segmentation tags, comprising:
- receiving a plurality of segmentation tags;
- generating block level tags in response to the received segmentation tags, each block level tag being a representative tag for a block of received segmentation tags;
- and
- cleaning selected ones of the received segmentation tags using a window of neighboring block level tags.

A segmentation tag cleanup system, comprising:
- a block tag generator connected to receive segmentation tags, the block tag generator generating block level tags in response to the received segmentation tags;
- and
- a pixel tag cleaner connected to receive the block level tags, the pixel tag cleaner cleaning selected ones of the received segmentation tags based upon a window of neighboring block level tags.
A system for processing video image data, 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 block tag generator connected to receive the segmentation tags from the segmentation processor, the block tag generator identifying a block of the received segmentation tags, compiling a statistic for the identified block and generating a block level tag for the block based on the compiled statistic;
- a pixel tag cleaner connected to receive block level tags, the pixel tag cleaner cleaning selected ones of the segmentation tags based upon a window of neighboring block level tags;
- and
- a marking engine connected to receive the video image data and the block tag, the marking engine generating an image on a receiving medium in response to the video image data and the block tag.
