Video Field Labeling

View page
US Patent:
6624844, Sep 23, 2003
Filed:
Aug 21, 2000
Appl. No.:
09/643309
Inventors:
Kevin Manbeck - Cranston RI
Chengda Yang - Auburndale MA
Donald Geman - Amherst MA
Stuart Geman - Providence RI
Assignee:
MTI Film LLC - Providence RI
International Classification:
H04N 718
US Classification:
348 97, 37524025, 348459
Abstract:
A method for determining labels for video fields by identifying the state of the field is disclosed. Some examples of a video fields state include the origin of the field as film or video, its relative location with respect to edit points, and in the case of film-originating material, the location within the standard sequential pattern which results from converting film to video. To determine the label of a video field, the conditional probability distribution for a particular sequence of states given the entire video sequence is calculated. This may be optimized by using dynamic programing to maximize the conditional probability function and thus the labels. To determine the conditional probability, first the joint probability distribution is determined for the observed video fields and the states. This joint probability is calculated by creating a data model and a structure model for the video sequence. From the joint probability distribution an equation representing the conditional probability of having a particular sequence of states given a particular video field is determined.

US Patent:
7064792, Jun 20, 2006
Filed:
Mar 29, 2001
Appl. No.:
09/821778
Inventors:
Chengda Yang - Auburndale MA, US
Kevin Manbeck - Cranston RI, US
Stuart Geman - Providence RI, US
Donald Geman - Amherst MA, US
Assignee:
MTI Film, LLC - Providence RI
International Classification:
H04N 7/01
H04N 11/20
US Classification:
348445, 348458
Abstract:
A method and computer program product for reformatting at least a portion of a digital source image. The digital source image has a number of pixels defining an original format which is to be converted to a destination image in a new format having a number of pixels. The number of pixels of the new format is greater than the number of pixels in the original format. A gradient is estimated at a point within a window which encompasses a plurality of intensity values from the source image. A polynomial is then used to determine a value for the point in the new format within the window. The polynomial is based in part upon the gradient. Values are then determined for additional points in the destination image by selecting a new window and repeating the acts of estimating a gradient and using a polynomial to determine a value.

Automated Color Control In Film-To-Digital Transfer

US Patent:
7068838, Jun 27, 2006
Filed:
Apr 17, 2002
Appl. No.:
10/124625
Inventors:
Kevin Manbeck - Cranston RI, US
Donald Geman - Amherst MA, US
Stuart Geman - Providence RI, US
Michael N. Orton - Agoura CA, US
Assignee:
MTI Film, LLC - Providence RI
International Classification:
G06K 9/00
US Classification:
382162, 382167, 348 96, 358522
Abstract:
A system and method for automatically adjusting color parameters during a film-to-digital transfer. An operator uses standard telecine equipment to preview scenes in order to determine a natural clustering of fields or scenes. Each cluster is processed separately. All the fields in a cluster are treated as one unit in the sense that color adjustments for the cluster are based on the cluster color histogram, which is computed by aggregating the colors from all pixels in the cluster. Constraints are specified for the cluster. Variables of a constraint may be automatically specified or determined by an operator based on observing sample frames from the cluster. In addition, the operator can nullify a constraint if desired. Within each cluster, the system adjusts red, green and blue intensities of the digitizing device, gains for each of these color channels, and other parameters. The system first determines which settings respect the constraints and then optimizes the solution.

High Resolution Color Conforming

US Patent:
7113223, Sep 26, 2006
Filed:
Apr 18, 2002
Appl. No.:
10/125651
Inventors:
Kevin Manbeck - Cranston RI, US
Jay Cassidy - Los Angeles CA, US
Stuart Geman - Providence RI, US
Donald Geman - Amherst MA, US
Donald McClure - Providence RI, US
Assignee:
MTI Film LLC - Providence RI
International Classification:
H04N 7/01
US Classification:
348453, 382167, 358523
Abstract:
A method, system and computer program product for color conforming video material at a given resolution is provided. The given video material is first converted to a lower resolution version of the same material. Then a color corrected version of the lower resolution version of the video material is obtained. A computer then analyzes the lower resolution version and the color corrected version of the lower resolution version in the same three dimensional color space to determine suitable color values for a color conforming version of the video material at the given resolution.

Cadence Editing

US Patent:
6542199, Apr 1, 2003
Filed:
Aug 21, 2000
Appl. No.:
09/643084
Inventors:
Kevin Manbeck - Cranston RI
Chengda Yang - Auburndale MA
Donald Geman - Amherst MA
Stuart Geman - Providence RI
Assignee:
MTI Film LLC - Providence RI
International Classification:
H04N 701
US Classification:
348459, 348441, 348458, 386 4, 386 52
Abstract:
A method for reordering an edited digital video sequence composed of digital video fields from multiple sources is disclosed. When the digital video sequence is reordered temporal cadence is provided which will allow for the conversion to a digital film format through a reverse 3:2 pulldown. Let F =(F ,F ,. . . ,F ) be the given edited sequence of video fields. In one embodiment, the method calculates an instruction set which is then used to transform F into a new sequence of video fields, denoted F , where most of the fields in F come from F and the remaining fields are âupconvertedâ fields from F. This reconstitution of F is obtained by optimizing a set of instructions based on various constraints which express the characteristics of the pattern AaBbBcCdDd. By assigning a cost to each violation of the constraints, and to each disruption of the natural flow of time, and to other undesirable properties, a real-valued function is constructed. This real valued function can then be optimized through dynamic programming.
