Abstract: A collaboration server hosts software for collaborative composition and editing of a media project with project collaborators using different media editing applications each having their own native data format. Project collaborators, such as video editors, sound editors, effects and graphics artists, and producers access a shared project workspace which contains a snapshot of the current state of the media project in a canonical format, as well as source media files, native application metadata, and change notes. Each editing application includes a module enabling it to read the canonical snapshot representation, and also to flatten its native data model representation into the canonical representation for writing to the shared project workspace. A collaboration server hosts the shared project space, and includes a workflow manager for issuing change notifications and handling versions, and an application server for the shared project user interface.

Abstract: A system and method for generating a representation of a color modification to be applied to segments on a digital nonlinear editing system, where each segment is a component of a media composition, and represents a section of a digital media. An indication of a modification to be applied to a color attribute of a segment is received, and the source from which the segment originates is identified. The indication of the color modification is then stored, and, as a result, the color modification is applied to other segments that originate from the identified source. Source color modification is applied to a section of a digital media on a digital nonlinear editing system. a media segment represents the section of a digital media. The segment is a component of a media composition, and originates from a source data structure. The source data structure also represents the section of the digital media. The section is received, and the first source data structure from which the segment originates is identified.

Abstract: A segmented array, perfectly aligned except for piston wraps, will have perfect imaging at wavelength ? but will have degraded imaging at other wavelengths. The present method detects and corrects piston wraps by making image-based measurements at a wavelength ? and a second wavelength ?1. These measurements will produce an image of the piston-wrapped segments and the intensities of these segments in the image at wavelength ?1 are linearly related to the sizes of the piston wraps at wavelength ?. The method needs no additional equipment like inter-segment apertures, lenslets, and detectors. It needs only a narrowband filter to change the measurement wavelength from ? to ?1.

Abstract: Automatic color correction is applied to a scene or clip, including a sequence of images, in a motion picture by selecting a representative image of the scene, analyzing the image and adjusting parameters of a color correction operation that is performed on the sequence of images included in the scene. This operation can be repeated automatically for all scenes or for selected scenes in the motion picture. The parameters may be adjusted to automatically color balance the image while maintaining substantially constant contrast. Analysis of the representative image may include identifying an offset of a peak in a two-dimensional histogram of the colors in the representative image from a white point. Parameters of a color correction operation are adjusted according to this offset. Separate histograms and offsets may be determined for shadows, midtones and highlight regions of the representative image.

Abstract: To make an intuitive interface for curves for color correction, a particular color is selected, such as gray, and the effect of each curve on pixels of that color may be displayed as a background image for the curve. A background image also may indicate a color to which tones corresponding to a selected and manipulated point of a curve will be modified or corrected. An image representing a gradient from the color component, through gray, to a complement of the color component may be displayed in association with the displayed function curve to suggest a result of color correction to be applied to the input image by manipulation of the function curve. A background image may suggest to the user what will happen if a point on the curve is moved. For example, if a user takes a point on the green curve that is in the center of the display and moves it to the lower right, the resulting image will have a magenta tint. The background image for the curve for the green channel shows more magenta in the lower right.

Abstract: A video camera with an adaptive optic device, digital images, and a sequential diversity processor can reduce the optical aberrations introduced by a changing optical medium so as to produce sharper clarified images. The change in the optics between sequential video frames is diversity information which allows the sequential diversity processor to estimate both the object under observation and the aberration. No additional information, such as a defocused image or other sensing device, is required. The concept could be used in any video camera which outputs digital images and uses a digital processor to control the adaptive optic device between sequential frames.

Abstract: Image-based, monochromatic, wavefront sensing for alignment of the segmented aperture of a telescope can produce segments which are misaligned by multiples of the center wavelength, ?. The phenomenon is well-known and it is called “piston ambiguity” [1]. We call such a misalignment a “piston wrap.” A segmented array, perfectly aligned except for piston wraps, will have perfect imaging at wavelength ? but will have degraded imaging at other wavelengths. The present method detects and corrects piston wraps by making image-based measurements at a second wavelength ?1. These measurements will produce an image of the piston-wrapped segments and the intensities of these segments are linearly related to the size of the piston wraps at wavelength ?. The method needs no additional equipment like inter-segment apertures, lenslets, and detectors. It needs only a narrowband filter to change the measurement wavelength from ? to ?1.

Abstract: An ellipsoid chroma region of a chroma plane may be defined to specify a range of chromas for which a secondary chroma modification is to be applied, and to determine an output chroma for each chroma of the chroma plane based on the ellipsoid chroma region. Further, two or more different-shaped chroma regions of a chroma plane may be defined and manipulated, each chroma region specifying a range of chroma for which a secondary chroma modification is to be applied, and to determine an output chroma for each chroma of the chroma plane based on the two or more different-shaped chroma regions. Also, chroma-matching techniques may be used to define and manipulate the chroma region of a chroma plane that specifies a range of chroma for which a secondary chroma modification is to be applied, and an output chroma may be determined for each chroma of the chroma plane based on the chroma region.

Abstract: Two images are analyzed to compute a set of motion vectors that describes motion between the first and second images. A motion vector is computed for each pixel in an image at a time between the first and second images. This set of motion vectors may be defined at any time between the first and second images, such as the midpoint. The motion vectors may be computed using any of several techniques. An example technique is based on the constant brightness constraint, also referred to as optical flow. Each vector is specified at a pixel center in an image defined at the time between the first and second images. The vectors may point to points in the first and second images that are not on pixel centers. The motion vectors are used to warp the first and second images to a point in time of an output image between the first and second images using a factor that represents the time between the first and second image at which the output image occurs.

Abstract: A graphical user interface facilitates color modification of a sequence of segments of moving images on a display of a general purpose computer. The graphical user interface may include a three-image display. The three image display may include a first region on the display for displaying an image from a current segment in the sequence to which a color modification is to be applied, a second region on the display and adjacent to the first region for displaying an image from a previous segment in the sequence before the current segment, and a third region on the display and adjacent to the first region for displaying an image from a next segment in the sequence after the current segment. A function screen allows a user to select a color modification to be performed to the current image. The function screen may include an interface that simultaneously displays a plurality of user modifiable graphs.

Abstract: To provide for more natural color matching and color correction, the ratio of the luminance of a pixel before correction to the luminance of the pixel after correction is computed. This ratio is used to scale the saturation of the corrected pixel, without changing its hue. For example, if the pixel is represented by a luminance component and two chrominance components, both of the chrominance components of the corrected pixel are scaled by the ratio. As a result, if the input luminance is lower than the luminance of the corrected pixel, then the saturation of the corrected pixel is reduced. If the input luminance is higher than the luminance of the corrected pixel, then the saturation of the corrected pixel is increased. The input luminance and scaled saturation of the corrected pixel are used to provide the components of an output pixel. As a result, the output pixel has the desired hue with a natural luminance and saturation.

Abstract: A system and method for generating a multi-tone representation of a digital image by applying a plurality of functions of luma to the digital image. The functions of luma comprise at least a first function and a second function, where each function has a value for each luma value in a range of luma values. Each function also has an associated display value. The digital image includes a plurality of pixels, where for each pixel, it is determined which of the first and second functions has a maximum value for a luma value of the pixel. Each pixel is represented using the display value associated with the determined function.
