Abstract
Methods and apparatus for embedding and recovering an image for use with video content are disclosed. An example apparatus includes an image processing module to embed a real component of a spectral representation of the image data into a first set of video frames from the plurality of video frames and embed an imaginary component of the spectral representation of the image data into a second set of video frames from the plurality of video frames.
Claims27
An apparatus to embed image data within a plurality of video frames comprising:
- an image processing module to use a processor to:
- embed a real component of a spectral representation of the image data into a first set of video frames from the plurality of video frames;
- and
- embed an imaginary component of the spectral representation of the image data into a second set of video frames from the plurality of video frames.
An apparatus to recover image data from a plurality of video frames comprising:
- a image recovery module to use a processor to:
- recover a real component of a spectral representation of the image data from a first set of video frames from the plurality of video frames;
- recover an imaginary component of the spectral representation of the image data from a second set of video frames from the plurality of video frames;
- and
- recover the image data based on the real component of the spectral representation of the image data and the imaginary component of the spectral representation of the image data.
A tangible computer readable medium having instructions stored thereon that, when executed, cause a machine to:
- embed a real component of a spectral representation of image data into a first set of video frames from a plurality of video frames to form a modified first set of video frames;
- and
- embed an imaginary component of the spectral representation of the image data into a second set of video frames from the plurality of video frames to form a modified second set of video frames.
