摘要： One or more facial recognition categories are assigned to a face region detected in an input image (24). Each of the facial recognition categories is associated with a respective set of one or more different feature extraction modules (66) and a respective set of one or more different facial recognition matching modules (76). For each of the facial recognition categories assigned to the face region, the input image (24) is processed with each of the feature extraction modules (66) associated with the facial recognition category to produce a respective facial region descriptor vector of facial region descriptor values characterizing the face region. A recognition result (96) between the face region and a reference face image (28) is determined based on application of the one or more facial recognition matching modules (76) associated with the facial recognition categories assigned to the face region to the facial region descriptor vectors produced for the face region detected in the input image (24).

摘要： Key technologies have been developed in realizing single longitudinal mode CW operation with a regular standing-wave cavity for intracavity frequency doubling and intracavity frequency conversions, so as to produce all solid-state, true cw devices with operation over wide spectral ranges including green, blue and UV. In one method laser arrangement, a beam expander (23 or 41) is applied to render a large mode waist and an improved beam divergence so as to greatly reduce the insertion losses for intracavity optical elements (17, 18 or 44). In another method laser arrangement, when spatial hole burning interference effect is minimized by using a pump head (12) with a thin gain zone (2) in contact with an end cavity mirror, then a low resolving-power spectral filter with low loss can be utilized. In addition, several novel optical multipass constructions, typically by use of total-internal-reflection, have also been devised for pumping laser chips, laser rods, laser slabs, and for the use of multipass optical amplifier and pumping fiber lasers.

摘要： An integrated optical fiber gyroscope chip based on surface Plasmon Polariton waveguide is an integrated optical fiber gyroscope chip in which optical signal is transmitted through the surface Plasmon Polariton waveguide and the polymer optical waveguide which are connected with each other, and it is used in the optical fiber gyroscope field. From the input end to the output end, the optical fiber gyroscope chip sequentially has: an input waveguide (1) and the third output waveguide (7), a directional coupler (2), a symmetrical triple waveguide splitter (3), the first output waveguide (61) and the second output waveguide (62), wherein the input waveguide (1), the first output waveguide (61), the second output waveguide (62) and the third output waveguide (7) are polymer optical waveguides, but the directional coupler (2) and the symmetrical triple waveguide splitter (3) are made from the surface Plasmon Polariton waveguide. The chip utilizes the transmission characteristics of the surface Plasmon Polariton waveguide to realize the single polarization of long-distance transmission of the optical signal, and directly modulates the surface Plasmon Polariton waveguide core layer, and removes influence of the leakage light to the precision of the fiber gyroscope through the specific structure.

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.
