Majid Rabbani: Method and apparatus for reducing quantization artifacts in a hierarchical image storage and retrieval system. Eastman Kodak Company, Peyton C Watkins, October 22, 1996: US05568570 (205 worldwide citation)

The system and method reduces the quantization artifacts in the addition and removal of a digital watermark to and from a selected resolution image of a hierarchical image storage system where the watermark removal record is placed in a higher resolution image component. For those applications where ...

Scott J Daly, Cheng Tie Chen, Majid Rabbani: Adaptive block transform image coding method and apparatus. Eastman Kodak Company, John D Husser, September 27, 1988: US04774574 (174 worldwide citation)

In a method and apparatus for transmitting a digital image over a limited bandwidth communication channel, an image is block transformed to produce blocks of transform coefficients; the transform coefficients are quantized in accordance with a model of the visibility of quantization error in the pre ...

Chris W Honsinger, Paul W Jones, Majid Rabbani, James C Stoffel: Lossless recovery of an original image containing embedded data. Eastman Kodak Company, Edward Dugas, Stephen H Shaw, August 21, 2001: US06278791 (145 worldwide citation)

The method and system embeds digital meta-data into an original image in such a way that the meta-data can be completely removed at a later time to allow loss less recovery of the original image. The loss less recovery of the original image allows for a digital signature of the image to be embedded ...

John R Squilla, Omid A Moghadam, Majid Rabbani: Photograhic system with selected area image authentication. Eastman Kodak Company, David M Woods, April 27, 1999: US05898779 (125 worldwide citation)

A public key encryption system for authenticating an image includes a digital camera having embedded therein a private key unique to the digital camera. A known public key uniquely based upon the private key is used to decrypt digital data encrypted with the private key to establish authenticity of ...

Chris W Honsinger, Majid Rabbani: Method for generating an improved carrier for use in an image data embedding application. Eastman Kodak Company, David M Woods, March 28, 2000: US06044156 (104 worldwide citation)

A message is embedded into a digital image by forming a digitized version of the message and convolving the digitized message with a random phase carrier to form a scrambled message. The scrambled message is then combined with the digital image to form an embedded message image that is near impossib ...

Majid Rabbani, Paul W Melnychuck: Method and associated apparatus for encoding bitplanes for improved coding efficiency. Eastman Kodak Company, Peyton C Watkins, August 15, 1995: US05442458 (83 worldwide citation)

An encoding method is described for image bitplanes whereby an arithmetic coder using conditioning contexts based on pixels from both the current bitplane and previously decoded bitplanes is employed. For the same number of contexts (which is important for minimizing memory usage), the method provid ...

Majid Rabbani, Rajan L Joshi, Kenneth A Parulski: Selectively adjusting the resolution levels or the quality levels of digital images stored in a digital camera memory. Eastman Kodak Company, Pamela R Crocker, April 26, 2005: US06885395 (78 worldwide citation)

A method for selectively adjusting the resolution levels or the quality levels of digital images stored in a memory of a digital camera having a predetermined memory space includes capturing a first image and storing the captured first image at a specific resolution level or quality level. The resol ...

Scott J Daly, Majid Rabbani, Cheng Tie Chen: Digital image compression and transmission system visually weighted transform coefficients. Eastman Kodak Company, Thomas H Close, October 25, 1988: US04780761 (76 worldwide citation)

A system for compressing and transmitting a digital image signal over a limited bandwidth communication channel, transform codes the image values and quantizes the transform coefficients according to a two-dimensional model of the sensitivity of the human visual system. The model of the human visual ...

Jonathan K Riek, Majid Rabbani, Arif T Erdem: Method and apparatus for encoding high-fidelity still images in MPEG bitstreams. Eastman Kodak Company, Thomas H Close, November 16, 1999: US05987179 (76 worldwide citation)

A frame in an uncompressed digital video signal is selected for encoding as a high-fidelity still image. The digital video signal is MPEG encoded to produce an MPEG encoded bitstream and additional bits are employed to encode the selected frame, to produce the MPEG encoded bitstream. The additional ...

Chris W Honsinger, Majid Rabbani, Paul W Jones: Method for efficient rate control. Eastman Kodak Company, David M Woods, March 12, 2002: US06356668 (72 worldwide citation)

An efficient method for determining the compressed rate of a digital image with a given set of compression parameters, the method comprises the steps of forming a plurality of non-overlapping image regions, each of which includes a plurality of contiguous pixels, from the digital image where the tot ...
