RAPID HIGH RESOLUTION ABSOLUTE 2-D ENCODING BY LOW RESOLUTION DIGITAL IMAGING OF A MATHEMATICALLY GENERATED 3-TONE TARGET

摘要

The feasibility and robustness of a 2-D absolute encoding/decoding architecture have been demonstrated. FPGA hardware processing will significantly reduce decoding time. A 3-tone scale, or a 2-tone approximation with reduced edge-defects, will further improve precision.
