    摘要: A cantilever beam structural resonant-type integrated optical waveguide accelerometer, includes an input waveguide (1), a dissymmetrical structural Mach-Zehnder interferometer (2), a micro-mechanical vibration cantilever beam (3), a short curved waveguide (4) and an output waveguide (5); all the waveguide structures and the cantilever beam use the integrated optical micromachining technique, and the device single-scale integration can be realized by using the temperature-insensitive organic polymer optical waveguide structure and the organic polymer substrate, the key technique indexes such as detection sensitivity, dynamic range are extensively adjusted. The phase difference of the optical signal can be measured by detecting the optical intensity of the resonant frequency of the optical circuit so as to achieve high sensitive acceleration detection, and to be free from the effect of the ambient temperature disturbance and waveguide birefringence.

    摘要: Systems and methods of detecting blocks of commercial content in video data are described. In one aspect, visual parameter values and audio parameter values are extracted from the video data. Visual boundary events, audio boundary events, and commercial content transition events are detected in the video data. Candidate commercial blocks of consecutive commercial content are detected in the video data from a combination of the detected visual boundary events and the detected audio boundary events. Each of the candidate commercial blocks is defined between respective candidate starting and ending boundary points. Ones of the starting and ending boundary points of the candidate commercial blocks are adjusted based on occurrence of one or more of the detected commercial content transition events within temporal windows respectively encompassing the starting and ending points.

    摘要: Camera motion is determined in a three-dimensional image capture system using a combination of two-dimensional image data and three-dimensional point cloud data available from a stereoscopic, multi-aperture, or similar camera system. More specifically, a rigid transformation of point cloud data between two three-dimensional point clouds may be more efficiently parameterized using point correspondence established between two-dimensional pixels in source images for the three-dimensional point clouds.

    摘要: Method, apparatus, and systems for extracting features from face regions and auxiliary identification regions of images are described. In one aspect, a face region containing at least a portion of a person's face is detected in an input image. An auxiliary identification region outside the face region is identified in the input image. Facial features characterizing the face region are determined. Auxiliary identification features characterizing the auxiliary identification region are calculated. An indexing datum is derived from the facial features and the auxiliary identification features. The indexing datum is stored in association with the input image.

    摘要: A method and system for automatic detection of the end of a video stream, wherein the energy level of the audio content is computed, a window at a time. The computed audio energy level is then compared against one or more audio energy level thresholds. Various features of the color content of the video content are then computed, a frame at a time. The computed color content is then compared against one or more video thresholds. Based on the results of the audio and video threshold comparisons, the end of the video stream can be automatically detected.

    摘要: A method and system for generating an audio thumbnail of an audio track in which a first content feature, such as singing, is detected as a characteristic of an audio track. A predetermined length of the detected portion of the audio track corresponding to the first content feature is extracted from the audio track. A highlight of the audio track, such as a portion of the audio track having a sudden increase in temporal energy within the audio track, is detected; and a portion of the audio track corresponding to the highlight is extracted from the audio track. The two extracted portions of the audio track are combined as a thumbnail of the audio track.
