Abstract
Methods and systems for spatial data encoding and decoding are described. A tile may be designated within a source frame. The tile may be divided into at least one bit area. A particular message bit value of a message may be accessed. A statistical property calculation may be performed on a pixel variable value of available pixels within the tile. A pixel variable value of pixels in the particular bit area of a target frame may be shifted to encode a particular message bit. A particular pixel variable value of a particular pixel of the plurality of pixels may be shifted by a shift value. The shift value may be in accordance with the statistical property calculation, the particular message bit value, and a particular modulation pattern value of the plurality of modulation pattern values for the particular pixel within the particular bit area.
