摘要： Human behavior is determined by sequential event detection by constructing a temporal-event graph with vertices representing adjacent first and second primitive images of a plurality of individual primitive images parsed from a video stream, and also of first and second idle states associated with the respective first and second primitive images. Constructing the graph is a function of an edge set between the adjacent first and second primitive images, and an edge weight set as a function of a discrepancy between computed visual features within regions of interest common to the adjacent first and second primitive images. A human activity event is determined as a function of a shortest distance path of the temporal-event graph vertices.

摘要： Determination of human behavior from an alignment of data streams includes acquiring visual image primitives from a video input comprising visual information relevant to a human activity. The primitives are temporally aligned to an optimally hypothesized sequence of primitives transformed from a sequence of transactions as a function of a distance metric between the observed primitive sequence and the transformed primitive sequence. More particularly, transforming includes comparing the distance metric costs and choosing and performing the lowest cost of temporally matching the observed primitives to one or more transactions, deleting a primitive, or associating a primitive with a pseudo transaction marker. Accordingly, alerts are issued based on analysis of the transformation of primitives.

摘要： Human behavior alerts are determined from a video stream through application of video analytics that parse a video stream into a plurality of segments, wherein each of the segments are either temporally related to at least one of a plurality of temporally distinct transactions in an event data log; or they are each associated with a pseudo transaction marker if not temporally related to at least one of the temporally distinct transactions and an image analysis indicates a temporal correlation with at least one of the distinct transactions is expected. Visual image features are extracted from the segments and one-SVM classification is performed on the extracted features to categorize segments into inliers or outliers relative to a threshold boundary. Event of concern alerts are issued with respect to the inlier segments associated with the associated pseudo transaction marker.

摘要： In an embodiment, automated analysis of video data for determination of human behavior includes providing a programmable device that segments a video stream into a plurality of discrete individual frame image primitives which are combined into a visual event that may encompass an activity of concern as a function of a hypothesis. The visual event is optimized by setting a binary variable to true or false as a function of one or more constraints. The optimized visual event is processed in view of associated non-video transaction data and the binary variable by associating the optimized visual event with a logged transaction if associable, issuing an alert if the binary variable is true and the optimized visual event is not associable with the logged transaction, and dropping the optimized visual event if the binary variable is false and the optimized visual event is not associable.

摘要： The present disclosure provides a rotary wireless network card with double rotating shafts, which comprises a wireless network card body, an ultra-thin USB interface and a first rotating shaft, wherein at the top of the wireless network card body a opening is provided to accommodate the ultra-thin USB interface as withdrawn; the ultra-thin USB interface extends out of or returns back to the opening by rotating around the first rotating shaft; inside the wireless network card body a rotating shaft support is provided; a second rotating shaft in the opening is rotatably connected to the rotating shaft support; the second rotating shaft is accommodated outside the ultra-thin USB interface and connected to the ultra-thin USB interface; and when the second rotating shaft rotates in the opening, the ultra-thin USB interface and the first rotating shaft rotate in the opening along with the second rotating shaft. By designing a rotary head, the present disclosure frees a USB from the external connection with a cap or other objects that are easily lost or broken, and as the rotary shaft of the ultra-thin USB interface is smaller than common rotary shafts, the whole wireless network card is much shorter and narrower, causing no interference on the use of a neighboring interface.
