Abstract
A method is employed that represents patterns using a super resolution encoding method that distributes the code value among adjacent pixels. One or more blocks are created, wherein each block is comprised of a plurality of bits, the height of the block is equal to the width of the block. One or more supercells are created by merging at least two adjacent blocks. One or more patterns are defined, wherein each pattern is defined by selecting one or more bits to be one of filled or unfilled within each supercell. Each of the one or more patterns is associated with an SRE code, the SRE code is related to the number and location of bits that are filled within the pattern. A pattern is defined with a plurality of patterns, each pattern is included in the one or more supercells.
