Appl. No.:

11/950869

Inventors:

Haiping Lu - Petaluma CA, US
Vincent Issier - Windsor CA, US
David Simons - Santa Rosa CA, US
Andy Miller - Windsor CA, US

Assignee:

JDS Uniphase Corporation - Milpitas CA

International Classification:

H01S 3/10

US Classification:

372 22, 372 21, 372 36, 372 2902, 372 29021, 372 31

Abstract:

A method and circuit is disclosed for a laser system wherein the power of the laser signal is kept at a constant near optimum value and a portion of an frequency doubled output signal is monitored and detected so that noise within the frequency doubled output signal can be minimized. A feedback signal is used to dither the temperature of a frequency doubled crystal so as to minimize the noise in the frequency doubled output signal.

Abstract:

A method for monitoring laser light launched into a core of a single mode fiber includes launching a portion of light directly into the cladding about the core. The cladding launched light is a known fraction of the core launched light and can be monitored by placing a detector about the cladding. Detected light including light that was launched into the cladding and has leaked through the cladding is used as a known fraction of light in the core and can be used to control the laser light source. This can be done with a straight section of single mode optical fiber and does not require bending the fiber. Advantageously, most of the core launched light remains in the core as guided light.

International Classification:

G06T 7/20

US Classification:

382107

Abstract:

Systems, methods, and computer-readable storage media for chatter reduction in video object segmentation using a variable bandwidth search region. A variable bandwidth search region generation method may be applied to a uniform search region to generate a variable bandwidth search region that reduces the search range for segmentation methods such as a graph cut method. The method may identify parts of the contour that are moving slowly, and reduce the search region bandwidth in those places to stabilize the segmentation. This method may determine a bandwidth for each of a plurality of local windows of an image according to an estimate of how much an object in the image has moved from a previous image. The method may blend the bandwidths for the plurality of local windows to generate a blended map. The method may then generate a variable bandwidth search region for an object according to the blended map.

Abstract:

Generation of parameterized avatars is described. An avatar generation system uses a trained machine-learning model to generate a parameterized avatar, from which digital visual content (e.g., images, videos, augmented and/or virtual reality (AR/VR) content) can be generated. The machine-learning model is trained to identify cartoon features of a particular style—from a library of these cartoon features—that correspond to features of a person depicted in a digital photograph. The parameterized avatar is data (e.g., a feature vector) that indicates the cartoon features identified from the library by the trained machine-learning model for the depicted person. This parameterization enables the avatar to be animated. The parameterization also enables the avatar generation system to generate avatars in non-photorealistic (relatively cartoony) styles such that, despite the style, the avatars preserve identities and expressions of persons depicted in input digital photographs.

Abstract:

Embodiments involve reducing collision-based defects in motion-stylizations. For example, a device obtains facial landmark data from video data. The facial landmark data includes a first trajectory traveled by a first point tracking one or more facial features, and a second trajectory traveled by a second point tracking one or more facial features. The device applies a motion-stylization to the facial landmark data that causes a first change to one or more of the first trajectory and the second trajectory. The device also identifies a new collision between the first and second points that is introduced by the first change. The device applies a modified stylization to the facial landmark data that causes a second change to one or more of the first trajectory and the second trajectory. If the new collision is removed by the second change, the device outputs the facial landmark data with the modified stylization applied.
