Abstract:
1. A method of designing a code book for super resolution encoding in an image rendering system, the method comprising: via a processor, creating a first group of entries in the code book that includes a plurality of gray font values for encoding data; via the processor, creating a second group of entries in the code book that includes a set of values for each of the gray font values for decoding data, wherein the sets of values in the second group of entries comprise target patterns configured to encode value mapping; via the processor, creating a third group of entries in the code book that includes a pattern corresponding to each of the plurality of gray font values; and storing the code book in a database in communication with the processor, wherein spacing between the target patterns and the corresponding encode values is optimized based on the frequency of the occurrences, wherein the more often a target pattern is selected, the wider the space between an adjacent encode value.
