Abstract
A set of symbols is encoded using a continuous mapping function to produce corresponding encoded functions, wherein the mapping function is continuous and values of the encoded functions are real and vary continuously. The encoded functions are summed in a spatial domain to generate a summed function, which is biased so that values of a biased function are all positive and real. Then, a physical property of the object is altered according the biased function to arrange a mark on the object.
