Patent number: 5629988Abstract: The invention is a system and method for electronic stabilization of a image produced by an electronic imaging device. The input may be any sequence of image frames from an image source, such as a video camera, an IR or X-ray imager, radar, or from a storage medium such as computer disk memory, video tape or a computer graphics generator. The invention can also be used with images from multiple sources when these must be stabilized with respect to one another. The invention uses a feedback loop and second image warp stage to achieve precise image alignment as part of the displacement estimation process. The output of the stabilization system is a modified image sequence in which unwanted components of image motion have been reduced or removed, or in which new motion of a desired form has been introduced.Type: GrantFiled: October 28, 1994Date of Patent: May 13, 1997Assignee: David Sarnoff Research Center, Inc.Inventors: Peter J.

Patent number: 5566251Abstract: Disclosed is a technique for deriving a composite video image by merging foreground and background video image data supplied from a plurality of separate video signal sources employing pattern-key insertion, rather than prior-art color-key insertion, for this purpose. Pattern-key insertion involves replacing a first pattern in a video scene with a second pattern. This is accomplished by first detecting the first pattern in the video scene and estimating the pose of this detected first pattern with respect to a reference object in the video scene. The second pattern is then geometrically transformed using the pose estimate of the detected first pattern. Finally, the detected first pattern is replaced with the geometrically-transformed second pattern.Type: GrantFiled: May 31, 1995Date of Patent: October 15, 1996Assignee: David Sarnoff Research Center, IncInventors: Keith J.

Patent number: 5488674Abstract: A method for fusing two or more source images to form a composite image with extended information content which may be color augmented and apparatus for forming the composite image from the source images is disclosed. Each source image is decomposed into a number of source images of varying resolution. The decomposed source images are analyzed using directionally sensitive operators to generate a set of oriented basis functions characteristic of the information content of the original images. The oriented basis functions for the composite image are then selected from those of the different source images and the inverse of the decomposition performed to construct the composite image. Color augmentation provides information as to the relative weighting of the contribution of each source to the composite image.Type: GrantFiled: May 12, 1993Date of Patent: January 30, 1996Assignee: David Sarnoff Research Center, Inc.Inventors: Peter J.

Patent number: 5159647Abstract: By processing the highest-resolution graphical data (e.g., image data) pertaining to relevant-objects defined by the graphical data into abstracted multiple-attribute information that is stored in a group of nodes of the lowest level of a hierarchy of data arrays (e.g., the leaf nodes of a complete data tree file), the present invention processes the data of each of these hierarchy of data arrays backward toward a single node of the highest level of the hierarchy of data arrays (e.g., the root node of a complete data tree file), to derive an attribute vector of all the abstracted multiple-attribute information at this single node. The derived attribute vector is then used to guide a search down the hierarchy of data arrays from the single node of its highest level toward at least a selected one of the group of nodes of its lowest level (which, by way of example, may correspond to the location of a likely relevant object).Type: GrantFiled: March 4, 1991Date of Patent: October 27, 1992Assignee: David Sarnoff Research Center, Inc.Inventor: Peter J.

Patent number: 5067014Abstract: An iterative process, implemented by a feedback loop, responds to all the image data in the respective analysis regions of three consecutive frames of a motion picture, to provide, after a plurality of cycles of operation thereof, an accurate estimation of the motion of either one or both of two differently moving patterns defined by the image data of these respective analysis regions. The analysis region of each frame is preferably large, and may occupy the entire frame area of a frame. The type of differently moving patterns include (1) separation by a motion bounty, (2) overlapping transparent surface in motion, (3) "picket fence" motion (4) masking of a small and/or low-contrast pattern by a dominant pattern, and (5) two-component aperture effects. Also, the operation of this iterative process inherently accurately estimates the motion of image data defining a single moving pattern.Type: GrantFiled: December 13, 1990Date of Patent: November 19, 1991Assignee: David Sarnoff Research Center, Inc.Inventors: James R.
