Edge Enhancement Correction For Improved Image Quality
View pageUS Patent:
6363526, Mar 26, 2002
Filed:
Apr 3, 1998
Appl. No.:
09/054955
Inventors:
Paul Vlahos - Tarzana CA
Arie Berman - Chatsworth CA
Arie Berman - Chatsworth CA
Assignee:
Ultimatte Corporation - Chatsworth CA
International Classification:
G06K 936
US Classification:
725 37, 348606, 348627, 348630, 348661, 382163, 382266, 382270
Abstract:
An objectionable outlining effect, seen as dark edges and white edges outlining everything in a scene, is eliminated by clipping or limiting the spikes generated by excessive enhancement. Specifically, a method is used for improving the quality of an enhanced video image, while simultaneously maintaining or improving image sharpness, by clipping the RGB levels of the enhanced video image, at the points of enhancement, to upper and lower level bounds representing the signal levels of the video signal prior to its enhancement.
Method And Apparatus For The Automatic Generation Of Subject To Background Transition Area Boundary Lines And Subject Shadow Retention
View pageUS Patent:
6667774, Dec 23, 2003
Filed:
Nov 2, 2001
Appl. No.:
10/008868
Inventors:
Arie Berman - Chatsworth CA
Paul Vlahos - Tarzana CA
Paul Vlahos - Tarzana CA
Assignee:
iMatte, Inc. - Chatsworth CA
International Classification:
H04N 5272
US Classification:
348584, 348586, 348598, 382167
Abstract:
Changes in a current image frame from variations in room light level, and automatic camera adjustments, are determined and incorporated into a clear (reference) frame, thereby resulting in a zero difference in the background region when the clear frame and a current frame are subtracted. Any deviation from zero defines the beginning edge of a transition from background to subject. The location of the outer edge of a transition area is further refined by subtracting derivatives of the RGB signals in each frame, and by the use of a fourth color channel when available. The difference of derivitives (d -d ) identifies the subject to background transition area, whose edges define the inner and outer boundary lines. Shadow areas on the backing are retained and may be transferred to the inserted background scene. Small areas on the backing having the same color and luminance as the subject are prevented from printing through the subject by a second âderivativeâ alpha channel for the small areas.
Generating An Inhibit Signal By Pattern Displacement
View pageUS Patent:
6789903, Sep 14, 2004
Filed:
Feb 18, 2003
Appl. No.:
10/370356
Inventors:
Joseph Parker - Camarillo CA
Paul Vlahos - Tarzana CA
Arie Berman - Chatsworth CA
Paul Vlahos - Tarzana CA
Arie Berman - Chatsworth CA
Assignee:
Imatte, Inc. - Chatsworth CA
International Classification:
G03B 2114
US Classification:
353 28, 353 97, 353122
Abstract:
A pattern is projected onto a screen by a projector using an illumination having a non-visible wavelength. A camera, displaced several inches from the projector, observes the projected pattern whose signals are then stored to create a reference frame. The pattern is then projected onto the screen a second time with a presenter present. The camera observes the projected pattern whose signals are then stored to create a current frame, including the presenter, and signals obtained from the reference frame are compared to determine their difference. In unobscured screen areas, the pattern images match. The pattern on the presenter is displaced because of the displaced camera, and no longer matches the reference pattern, thereby identifying the presenters silhouette area.
Comprehensive Method For Removing From An Image The Background Surrounding A Selected Subject
View pageUS Patent:
61343455, Oct 17, 2000
Filed:
Aug 28, 1998
Appl. No.:
9/141703
Inventors:
Arie Berman - Chatsworth CA
Paul Vlahos - Tarzana CA
Paul Vlahos - Tarzana CA
Assignee:
Ultimatte Corporation - Chatsworth CA
International Classification:
G06K 900
US Classification:
382162
Abstract:
In most cases, the estimated subject color and/or the estimated background color for a given pixel will have a certain amount of error, which could result in either not enough background removal, or removal of all of the background and some of the foreground. By manually or automatically altering the estimated subject color and/or background color, the errors in matte calculation and subsequent removal of the background, can be minimized or eliminated. Manual alteration of a subject or background color is achieved by using a cursor to select a true color from the background, for example, and inserting it in one or more areas in the background area being partially obscured by the subject. Automatic alteration of one of the estimated subject or background colors involves its computation as a projection in color space of the observed transition pixel color, onto a plane defined by the subject and background reference colors or other defined planes. By treating the shadow as a semitransparent subject, a matte (alpha channel) may be generated to represent the shadow's transition densities, thus permitting the shadow to be regenerated over the new background.
Method For Removing From An Image The Background Surrounding A Selected Object
View pageUS Patent:
61343463, Oct 17, 2000
Filed:
Jan 16, 1998
Appl. No.:
9/008270
Inventors:
Arie Berman - Chatsworth CA
Paul Vlahos - Tarzana CA
Paul Vlahos - Tarzana CA
International Classification:
G06K 900
G09G 500
G09G 500
US Classification:
382163
Abstract:
A computer implemented method to extract a selected subject from its background, by removing the background, including that portion of the background visible through semi transparent areas of the subject, and generating a matte signal containing a record of background levels outside of and within semitransparent subject areas. The observed RGB signal levels of a pixel in the semitransparent transition between a subject and its background, are a mixture of color contributed by the subject, and by the background. The estimated subject color, and the estimated background color, and the observed color of a transition pixel (pixRGB), may be shown as three points in a three dimensional color space.
Method For Removing From An Image The Background Surrounding A Selected Subject By Generating Candidate Mattes
View pageUS Patent:
62887033, Sep 11, 2001
Filed:
May 24, 1999
Appl. No.:
9/317358
Inventors:
Arie Berman - Chatsworth CA
Paul Vlahos - Tarzana CA
Paul Vlahos - Tarzana CA
Assignee:
Ultimatte Corporation - Chatsworth CA
International Classification:
G09G 500
US Classification:
345150
Abstract:
In an image being displayed on a monitor, each observed background color is identified using a cursor to select the dominant colors. Each foreground color is also identified by using the cursor as a selector. For each pixel, several Candidate mattes are computed one for each background color. Each Candidate matte is computed from a single background color and the set of selected foreground colors using any known method. Of the several Candidate mattes, the greater of these Candidates becomes the matte signal for a given pixel. If this matte is 1. 0, then the pixel is part of the background. If the matte is zero, then the pixel is part of the subject. If the matte is between 1. 0 and 0. 0, then the pixel is in a transition area and the contribution of the background to the pixel is that pixel's matte level. A `Processed Foreground` is generated by removing the contribution of the background from each pixel in the image, resulting in the subject appearing against a black field.
Backing Luminance Non-Uniformity Compensation In Real-Time Compositing Systems
View pageUS Patent:
59401400, Aug 17, 1999
Filed:
Sep 10, 1996
Appl. No.:
8/709254
Inventors:
Arie Berman - Canoga Park CA
Paul Vlahos - Tarzana CA
Paul Vlahos - Tarzana CA
Assignee:
Ultimatte Corporation - Chatsworth CA
International Classification:
H04N 975
H04N 5272
H04N 5272
US Classification:
348587
Abstract:
A method of removing the foreground subject and its shadow from a series of image frames including a subject before a colored backing being photographed by a moving camera during a live broadcast. Such removal results in a series of image frames of the colored backing without the subject, each image frame corresponding to an image frame containing the subject. The method steps employed identify, for each frame, those pixels in the frame occupied by elements of the subject. Those pixels are set to an RGB level of zero, to create an image of the colored backing in which the subject area is reduced to black. The image of the colored backing is then smeared to obliterate the defined edges of the subject's shadow and to smear the color of the backing into the black area previously occupied by the subject to generate a clear frame. The clear frame is then utilized to compensate for backing luminance and color nonuniformity, thereby preventing visibility of the joining edge of generated windows that extend the backing to the edge of the frame.
