Abstract

The present invention provides a method and apparatus for classifying image data. A white class detector may receive input image data and determine a white class of a specified pixel based on local roughness, peak or count or valley count and a brightness. A pattern detection device may detect a pattern of pixels across a scan line or matrix of input data and compare the pattern with a plurality of predetermined pixel patterns.
