Patent number: 10242267Abstract: 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: GrantFiled: May 24, 2016Date of Patent: March 26, 2019Assignee: International Business Machines CorporationInventors: Quanfu Fan, Sachiko Miyazawa, Sharathchandra U.

Patent number: 9569672Abstract: 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: GrantFiled: October 16, 2015Date of Patent: February 14, 2017Assignee: International Business Machines CorporationInventors: Russell P.

Patent number: 9355308Abstract: 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 to make the true or false determination, then additional data is presented from the visual image stream for review.Type: GrantFiled: October 17, 2014Date of Patent: May 31, 2016Assignee: GlobalFoundries, Inc.Inventors: Quanfu Fan, Zuoxuan Lu, Sachiko Miyazawa, Sharathchandra U.

Patent number: 8681232Abstract: 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: GrantFiled: August 26, 2011Date of Patent: March 25, 2014Assignee: International Business Machines CorporationInventors: Quanfu Fan, Prasad Gabbur, Sachiko Miyazawa, Sharathchandra Pankanti, Hoang Trinh

Patent number: 8682032Abstract: 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: GrantFiled: August 19, 2011Date of Patent: March 25, 2014Assignee: International Business Machines CorporationInventors: Quanfu Fan, Prasad Gabbur, Sachiko Miyazawa, Jiyan Pan, Sharathchandra U.
