Automated segmentation tuner

A system for processing an image region of an image having a plurality of pixels, comprising:

• a processor that:
• divides the image region into a plurality of bricks of pixels;
• calculates parameters of the plurality of bricks;
• applies the calculated parameters of each brick to a plurality of brick parameter separation equations to obtain a result for each of the plurality of brick parameter separation equations;
• computes an index for each brick by concatenating the brick parameter separation equation evaluation results for that brick];
• performs a classification map lookup using the index;
• and
• classifies the brick as representing white space, black text, or image content according to the result of the classification map lookup;
• whereby
• the image region is segmented into sub-regions of white space, black text, and image content according to the classification of said bricks.

A non-transitory machine-readable medium embodying a computer program product for processing an image region of an image having a plurality of pixels, the non-transitory machine-readable medium comprising non-transitory program instructions that, when executed by a computer, cause the computer to:

• divide the image region into a plurality of bricks of pixels;
• calculate parameters of the plurality of bricks;
• apply the calculated parameters of each brick to a plurality of brick parameter separation equations to obtain a result for each of the plurality of brick parameter separation equations;
• compute an index for each brick by concatenating the brick parameter separation equation evaluation results for that brick;
• perform a classification map lookup using the index;
• and
• classify the brick as representing white space, black text, or image content according to the result of the classification map lookup;
• whereby
• the image region is segmented into sub-regions of white space, black text, and image content according to the classification of said bricks.

A system for processing at least one image region of an image having a plurality of pixels, comprising means for:

• dividing the image region into a plurality of bricks of pixels;
• calculating parameters of each of the plurality of bricks;
• applying in a computer system the calculated parameters of each brick to a plurality of brick parameter separation equations to obtain a result for each of the plurality of brick parameter separation equations;
• computing an index for each brick by concatenating the brick parameter separation equation results for that brick;
• performing a classification map lookup using the index;
• and
• classifying the brick as representing white space, black text, or image content according to the result of the classification map lookup;
• whereby
• the image region is segmented into sub-regions of white space, black text, and image content according to the classification of said bricks.
