Publication number: 20140037143Abstract: Video analytics data is audited through review of selective subsets of visual images from a visual image stream as a function of a temporal relationship of the images to a triggering alert event. The subset comprehends an image contemporaneous with the triggering alert event and one or more other images occurring before or after the contemporaneous image. The generated subset may be presented for review to determine whether the triggering alert event is a true or false alert, or whether additional data from the visual image stream is required to make such a determination. If determined from the presented visual essence that the additional data is required make the true or false determination, then additional data is presented from the visual image stream for review.Type: ApplicationFiled: October 14, 2013Publication date: February 6, 2014Applicant: International Business Machines CorporationInventors: Quanfu Fan, Zuoxuan Lu, Sachiko Miyazawa, Sharathchandra U.

Publication number: 20140009620Abstract: Transaction units of video data and transaction data captured from different checkout lanes are prioritized as a function of lane priority values of respective ones of the different checkout lanes from which the transaction units are acquired. Each of the checkout lanes has a different lane priority value. The individual transaction units are processed in the prioritized processing order to automatically detect irregular activities indicated by the transaction unit video and the transaction data of the processed individual transaction units.Type: ApplicationFiled: September 10, 2013Publication date: January 9, 2014Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Russell P.

Publication number: 20130336531Abstract: Human behavior is determined by sequential event detection by constructing a temporal-event graph with vertices representing primitive images of images of a video stream, and also of idle states associated with the respective primitive images. A human activity event is determined as a function of a shortest distance path of the temporal-event graph vertices.Type: ApplicationFiled: August 16, 2013Publication date: December 19, 2013Applicant: International Business Machines CorporationInventors: Russell P.

Patent number: 8582803Abstract: 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.Type: GrantFiled: October 15, 2010Date of Patent: November 12, 2013Assignee: International Business Machines CorporationInventors: Lei Ding, Quanfu Fan, Prasad Gabbur, Arun Hampapur, Sachiko Miyazawa, Sharathchandra U.

Patent number: 8548203Abstract: 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.Type: GrantFiled: July 12, 2010Date of Patent: October 1, 2013Assignee: International Business Machines CorporationInventors: Russell P.

Publication number: 20130250115Abstract: Embodiments of the present invention provide a system, method, and program product to determine whether a product has been successfully purchased by identifying in a video record when a movement of a product adjacent to a scanner occurs, and whether the scanner did not record a purchase transaction at that time; measuring a difference in time between the time of the movement of the product and a time of another movement of a product, and determining by a trained support vector machine a likelihood that the product was successfully purchased. Alternately, the difference in time can be measured between the time of the movement of the product and a time of a transaction record, or between the time of the movement of the product and a boundary time. The support vector machine can use a radial basis function kernel and can generate a decision value and a confidence score.Type: ApplicationFiled: March 23, 2012Publication date: September 26, 2013Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Quanfu Fan, Sachiko Miyazawa, Sharathchandra U.

Publication number: 20130050517Abstract: Visual content in images captured from a scene by a camera in each of a plurality of different pose settings are analyzed to determine predicted occurrences of a transaction associated with the visual content in each pose, which are compared with actual transaction occurrence data to generate performance values for each pose as a function difference between the predicted and actual transactions. Optimized poses are chosen having the best performance value, wherein a camera controller may place the camera in the optimum pose for use in monitoring the scene and generating the primitives of interest associated with the transactions.Type: ApplicationFiled: August 26, 2011Publication date: February 28, 2013Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Quanfu Fan, Prasad Gabbur, Sachiko Miyazawa, Sharathchandra U.

Publication number: 20130044942Abstract: Events are classified through string pattern recognition. Text labels are assigned to image primitives in a time-ordered set of training images and to related time-ordered transactions in an associated training transaction log in a combined time-ordered training string of text labels as a function of image types. Transactions are labeled in a training transaction log with a transaction label, a training primitive image of a start of a transaction with a start image text label, a training primitive of an entry of a transaction into the log with an entry image text label, and a training primitive of a conclusion of a transaction with an ending image text label. Positive subset string patterns are discovered representing true events from the combined time-ordered training string of text labels, and negative subset string patterns defined by removing single transaction primitive labels from the positive subset string patterns.Type: ApplicationFiled: August 19, 2011Publication date: February 21, 2013Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Quanfu Fan, Prasad Gabbur, Sachiko Miyazawa, Jiyan Pan, Sharathchandra U.

Publication number: 20120293661Abstract: An approach to reduce the processing power required to monitor check-out stations. A subset of check-out stations may be monitored at any given time, instead of monitoring all check-out stations at all times. The subset of check-out stations is determined dynamically according to, but not limited to, cashier records, input parameters from the user, current lane activity, past lane activity, time of day, etc. Statistical models (e.g., effective population sampling and/or population hypothesis tests) are developed along these lines that guide the lane selection process, whereby increases in the false-negative rate due to failure to monitor particular lanes when events of interest occur are controlled. By monitoring fewer check-out stations, while maintaining target performance accuracy, the amount of data that end users must deal with is significantly reduced.Type: ApplicationFiled: July 27, 2012Publication date: November 22, 2012Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Russell Patrick Bobbitt, Quanfu Fan, Sachiko Miyazawa, Sharathchandra Umapathirao Pankanti, Yun Zhai
