Patent number: 11354683Abstract: A method and system for creating an anonymous shopper panel based on multi-modal sensor data fusion. The anonymous shopper panel can serve as the same traditional shopper panel who reports their household information, such as household size, income level, demographics, etc., and their purchase history, yet without any voluntary participation. A configuration of vision sensors and mobile access points can be used to detect and track shoppers as they travel a retail environment. Fusion of those modalities can be used to form a trajectory. The trajectory data can then be associated with Point of Sale data to form a full set of shopper behavior data. Shopper behavior data for a particular visit can then be compared to data from previous shoppers' visits to determine if the shopper is a revisiting shopper. The shopper's data can then be aggregated for multiple visits to the retail location. The aggregated shopper data can be filtered using application-specific criteria to create an anonymous shopper panel.Type: GrantFiled: December 30, 2015Date of Patent: June 7, 2022Assignee: VideoMining CorporationInventors: Joonhwa Shin, Rajeev Sharma, Youngrock R Yoon, Donghun Kim

Publication number: 20200380274Abstract: In various examples, image areas may be extracted from a batch of one or more images and may be scaled, in batch, to one or more template sizes. Where the image areas include search regions used for localization of objects, the scaled search regions may be loaded into Graphics Processing Unit (GPU) memory and processed in parallel for localization. Similarly, where image areas are used for filter updates, the scaled image areas may be loaded into GPU memory and processed in parallel for filter updates. The image areas may be batched from any number of images and/or from any number of single- and/or multi-object trackers. Further aspects of the disclosure provide approaches for associating locations using correlation response values, for learning correlation filters in object tracking based at least on focused windowing, and for learning correlation filters in object tracking based at least on occlusion maps.Type: ApplicationFiled: May 29, 2020Publication date: December 3, 2020Inventors: Joonhwa Shin, Zheng Liu, Kaustubh Purandare

Patent number: 10614436Abstract: A method and system for associating a mobile device carried by a shopper with Point-of-Sale (PoS) data from that shopper's transaction at a retail location. Specifically, the association can utilize face data that was associated with the mobile device to match face data that was generated by association with PoS data. The association with a mobile device can also include the calculation of a mobile trajectory to enable the generation of a shopper profile including shopper behavior. The mobile to PoS association can include tracking of the mobile device throughout a retail location to form a trajectory. The association of a face to a mobile device can utilize the device's MAC address and repeat visit analysis to determine a match. The association of a face to PoS data can utilize the aligning of event time series based on a dynamic time disparity to match checkout events with PoS events.Type: GrantFiled: August 25, 2016Date of Patent: April 7, 2020Assignee: VideoMining CorporationInventors: Rajeev Sharma, Joonhwa Shin, Youngrock Yoon, Donghun Kim

Patent number: 10262331Abstract: A method and system for cross-channel shopper behavior analysis. Tracking individual shopper behavior across many retail locations (i.e., across multiple channels) can be extremely valuable for product manufacturers and retails. A configuration of vision sensors and mobile access points can be used to detect and track shoppers as they travel a retail environment, forming a trajectory. The trajectory data can then be associated with Point of Sale data to form a full set of shopper behavior data. The shopper's data can then be aggregated for multiple visits to many retail locations in a geographic area. The aggregated shopper data can be filtered using application-specific criteria for further analysis.Type: GrantFiled: January 29, 2016Date of Patent: April 16, 2019Assignee: VideoMining CorporationInventors: Rajeev Sharma, Joonhwa Shin, Youngrock R Yoon, Donghun Kim

Patent number: 10198625Abstract: A method and system for associating a physically identifiable feature of a person with the unique identifier of a mobile device carried by the person as detected across repeat visits to a physical location or multiple locations. Specifically, associating the face of a repeat visitor with a unique identifier of a mobile device, such as the device's MAC address, by means of a repeat visit analysis without any explicit or voluntary participation of the person, for example, in a form of providing their information by participation in a survey. For each detection of a particular MAC address associated with a mobile device at a particular physical location, a set of candidate faces can be captured at that physical location. Revisiting faces can be identified and grouped together, and a probability that each group of faces is associated with a particular MAC address can then be calculated.Type: GrantFiled: March 26, 2016Date of Patent: February 5, 2019Assignee: VideoMining CorporationInventors: Joonhwa Shin, Rajeev Sharma, Donghun Kim

Patent number: 10083358Abstract: A method and system for associating an image of a face of at least a person with Point-of-Sale (PoS) data by aligning a first event time series with a second event time series based on a dynamic time disparity. An exemplary embodiment can generate an event time series containing facial recognition data for a person or persons during the PoS transaction process. These data can form a vision-based checkout event time series. An embodiment can also collect PoS transaction data from the retail checkout system, using timestamp information to create a second event time series. As there may be a time disparity between the time series, they can then be aligned in order to match events from one time series to the other. Faces identified in checkout events in the first time series can be registered to PoS events and the results stored in a database.Type: GrantFiled: July 26, 2016Date of Patent: September 25, 2018Assignee: VideoMining CorporationInventors: Joonhwa Shin, Rajeev Sharma, Youngrock Yoon, Donghun Kim

Patent number: 9161084Abstract: The present invention provides a comprehensive method to design an automatic media audience measurement system that can estimate the site-wide audience of a media of interest (e.g., the site-wide viewership of a target display) based on the measurements of a subset of the actual audience sampled from a limited space in the site. This invention enables (1) the placement of sensors in optimal positions for the viewership data measurement and (2) the estimation of the site-wide viewership of the target display by performing the viewership extrapolation based on the sampled viewership data. The viewership extrapolation problem is formulated in a way that the time-varying crowd dynamics around the target display is an important decisive factor as well as the sampled viewership data at a given time in yielding the estimated site-wide viewership.Type: GrantFiled: October 29, 2013Date of Patent: October 13, 2015Assignee: VideoMining CorporationInventors: Rajeev Sharma, Namsoon Jung, Joonhwa Shin
