Abstract:
A method of forming an encoded configuration for a data glyph block containing one or more occlusions, comprisingperforming cut off of an occlusion when the occlusion is within one frame size of a border of the data glyph block and when fewer bytes are lost through cut off than through error correction of the occlusion, subsequent to performing cut off, performing one or both of enlargement of an occlusion to cross two consecutive synchronization lines in both x and y directions when the occlusion does not cross two consecutive synchronization lines in both x and y directions and when fewer bytes are lost through enlargement than through error correction of the occlusion, and merger of two or more occlusions when the two or more occlusions are located within one frame distance from one another and when fewer bytes are lost through merger than through error correction of the occlusions, encoding the cut off, enlarged or merged occlusions with synchronization lines, and encoding any remaining occlusions by error correction, thereby forming the encoded configuration.
