This document describes tools for inputting data into a computer via the movement of features of a user as detected by a webcam or other input device. This is accomplished by a user moving his or her features in view of a webcam. The webcam or other input device then detects the presence and motion of the feature(s) and converts these motions into input signals to execute predetermined input instructions.

Techniques for providing real-time animation for a personalized cartoon avatar are described. In one example, a process trains one or more animated models to provide a set of probabilistic motions of one or more upper body parts based on speech and motion data. The process links one or more predetermined phrases that represent emotional states to the one or more animated models. After creation of the models, the process receives real-time speech input. Next, the process identifies an emotional state to be expressed based on the one or more predetermined phrases matching in context to the real-time speech input. The process then generates an animated sequence of motions of the one or more upper body parts by applying the one or more animated models in response to the real-time speech input.

A “Transform Invariant Low-Rank Texture” (TILT) Extractor, referred to as a “TILT Extractor” accurately extracts both textural and geometric information defining regions of low-rank planar patterns from 2D images of a scene, thereby enabling a large range of image processing applications. Unlike conventional feature extraction techniques that rely on point-based features, the TILT Extractor extracts texture regions from an image and derives global correlations or transformations of those regions in 3D (e.g., transformations including translation, rotation, reflection, skew, scale, etc.). These image domain transformations inherently provide information relative to an automatically determinable camera viewing direction. In other words, the TILT Extractor extracts low-rank regions and geometric correlations describing domain transforms of those regions relative to arbitrary camera viewpoints. The TILT Extractor also identifies sparse error in image intensity or other color channels resulting from noise, occlusions or other artifacts, thereby allowing elimination or reduction of such errors in images.

The related links recommendation technique described herein employs combined collaborative filtering to recommend related web pages to users. The technique creates multiple collaborative filters which are combined in order to create a combined collaborative filter to recommend web pages similar to a given web page to a user. One query-based collaborative filter is created by using query search clicks (e.g., user input device selection actions on search results returned in response to a search query). Another user-behavior-based collaborative filter is created by using query search clicks and user clicks while browsing websites (e.g., user input device selection actions while a user is browsing websites). Lastly, another content-based collaborative filter based on similar content of web pages is created by finding web pages with similar content.

An apparatus and method for analyzing biological cells and other particles using an external laser cavity. Microfluidic channels contain and transport biological cells to be analyzed. A laser diode provides light for cell analysis. An external cavity is provided between one surface of the laser diode and a mirror opposite thereto. A microlens set focuses the light on only one cell as it passes through the external cavity. The presence of the cell in the external cavity gives a weak feedback toward the laser diode. The emission frequency and the output power of the laser are both functions of the length of the external cavity. Therefore, the variation of cavity length can be deduced from these parameters, where the variation is caused by changing the refractive index or size of the cell in the cavity.

A computing system and method updates firmware to a baseboard management controller (BMC) of a motherboard. The computing system updates firmware of the BMC according to the parameters, wherein the parameters includes a predetermined number of times to update the firmware of the BMC. The computing system counts a number of successful updates, in response to a determination that a current update of the firmware is successful. The computing system records information of each of the successful updates and generates a log file for storing the information, in response to a determination that counted number of the successful updates equal to the predetermined number of times.
摘要:
A “Text Rectifier” provides various techniques for processing selected regions of an image containing text or characters by treating those images as matrices of low-rank textures and using a rank minimization technique that recovers and removes image deformations (e.g., affine and projective transforms as well as general classes of nonlinear transforms) while rectifying the text or characters in the image region. Once distortions have been removed and the text or characters rectified, the resulting text is made available for a variety of uses or further processing such as optical character recognition (OCR). In various embodiments, binarization and/or inversion techniques are applied to the selected image regions during the rank minimization process to both improve text rectification and to present the resulting images of text to an OCR engine in a form that enhances the accuracy of the OCR results.
