Patent number: 8947744Abstract: A print media (200) comprises paper or other substrate, on which image content, whether text or images are printed with accompanying hidden data (220). The image content is printed with one or more normal printing process visible colorants (340), while the hidden data (220) is printed with spectral edge markers (320). The spectral edge marker materials (320) have a substantial spectral absorption just outside the human visible spectrum, and only slight visible absorption, which is masked by the visible colorants (340). Although the hidden data is nominally visually imperceptible, an image capture device (250) having a visible spectral response that extends into a spectral region just outside the visible spectrum where the spectral edge marker absorption occurs, can then detect the hidden data.Type: GrantFiled: June 19, 2012Date of Patent: February 3, 2015Assignee: Eastman Kodak CompanyInventors: Andrew F. Kurtz, Kurt M. Schroeder, Majid Rabbani

Patent number: 8941886Abstract: A method for providing digital watermarking for text or images that uses spectral edge marking materials (320) printed on a print media (200) to embed hidden data (220). The spectral edge markers (320) have an absorption spectrum at the edge of the human visible spectrum, either at the UV edge or IR edge, which provides an optical density that is generally imperceptible to humans, but which can be detected by an image capture device (250). The crosstalk of visible optical absorption provided by these materials is largely masked by the presence of visible colorant(s) (340), with only small color differences between areas with and without the spectral edge markers (320). The image capture device (250) has a visible spectral response that extends into a spectral region just outside the visible spectrum where the spectral edge marker absorption occurs, and can be operated to detect the hidden data.Type: GrantFiled: June 19, 2012Date of Patent: January 27, 2015Assignee: Eastman Kodak CompanyInventors: Andrew F.

Patent number: 8031775Abstract: In order to analyze a digital video clip to determine candidate frames for subsequent key frame selection, a camera motion sensor is provided in the camera so that information is provided during image capture regarding camera motion including translation of the scene or camera, or scaling of the scene. The sensor includes an accelerometer or a lens motor sensor. A plurality of video segments is formed based on the global motion estimate and each segment is labeled in accordance with a predetermined series of camera motion classes. Thereafter, key frame candidates are extracted from the labeled segments and a confidence score is computed for each candidate by using rules corresponding to each camera motion class and a rule corresponding to object motion.Type: GrantFiled: February 3, 2006Date of Patent: October 4, 2011Assignee: Eastman Kodak CompanyInventors: Jiebo Luo, Christophe E.

The multiple image sensors capture data with one or more different characteristics, such as: staggered exposure periods, different length exposure periods, different frame rates, different spatial resolution, different lens systems, and different focal lengths. The data from multiple image sensors is processed and interleaved to generate an improved output motion sequence relative to an output motion sequence generated from an a single equivalent image sensor.Type: GrantFiled: March 1, 2007Date of Patent: July 12, 2011Assignee: Eastman Kodak CompanyInventors: Aaron T.

Patent number: 7755667Abstract: In an image sequence stabilization method and a camera, a sequence of input digital images are captured. The sequence of input digital images is replicated to provide a corresponding sequence of archival images and a corresponding sequence of display images. The archival image sequence is automatically stabilized to provide a stabilized archival image sequence. The display image sequence is automatically stabilized to provide a stabilized display image sequence. The stabilization methods used for the two sequences are different, although both can be digital.Type: GrantFiled: May 17, 2005Date of Patent: July 13, 2010Assignee: Eastman Kodak CompanyInventors: Majid Rabbani, Aaron T.

Patent number: 7382926Abstract: A JPEG2000 compressed image is transcoded to a lower bit-rate or lower resolution, or both, without having to decompress the initial JPEG2000 image and then recompress it to a lower bit-rate and/or resolution. Instead, arithmetic decoding is performed only to the nearest higher bit-rate layer, up to the desired resolution, before performing rate-distortion optimization to produce the transcoded image.Type: GrantFiled: June 30, 2004Date of Patent: June 3, 2008Assignee: Eastman Kodak CompanyInventors: Rajan L.
