Methods and systems for echo modulation are described. In one embodiment, intensities of a plurality of values in multiple windows of an audio signal may be obtained. The windows may be subject to a periodic boundary condition. A plurality of echo values may be calculated for each of the respective windows. The audio signal may be altered in one or more of the windows using a windowing function and echo values. Additional methods and systems are disclosed.

Echo modulation methods and system

Echo modulation methods and systems

Methods and systems for image registration are described. An area of an image may be selected. A length of at least one encoded wavelength for the area may be accessed. One or more candidate wavelengths may be identified in the area in at least one direction that includes at least one large peak. The length of the at least one encoded wavelength may be compared to the length of at least one of the one or more candidate wavelengths to calculate an alteration ratio. The alteration ratio may identify at least one of a scale or a rotation of the image.

Method and system for image registration

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.
