Patents by Inventor Ahmet Murat Tekalp

Ahmet Murat Tekalp has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • System and method for embedding information in digital signals
    Patent number: 6895101
    Abstract: A lossless, reversible data embedding technique uses a generalization of least-significant-bit modification. The portions of the signal that are susceptible to embedding distortion are compressed and sent as part of the embedded payload. A prediction-based conditional entropy coder uses unaltered portions of the host signal to improve lossless data capacity.
    Type: Grant
    Filed: June 30, 2003
    Date of Patent: May 17, 2005
    Assignees: University of Rochester, Xerox Corporation
    Inventors: Mehmet Utku Celik, Gaurav Sharma, Ahmet Murat Tekalp
