The present disclosure provides a method and device for identifying a product purchased by a user and intelligent shelf system. The method includes acquiring a weight of products carried in a container, acquiring a first monitoring image acquired in a monitoring area corresponding to the container, identifying the first monitoring image, and obtaining an identification result, wherein the identification result comprises user identity information when it is determined that the weight of the products is reduced, acquiring a time when at least one product carried in the container is picked up, and determining information of at least one picked-up product, obtaining the user identity information corresponding to the at least one picked-up product, and associating the user identity information with the information of the at least one picked-up product.

Method and device for identifying product purchased by user and intelligent shelf system

A person tracking method, comprising: acquiring N frames in units of time windows; acquiring, in time windows, tracking paths of a target person according to the N frames; and constructing continuous tracking paths by means of continuous time windows, so as to obtain the tracking results of the target person.

Person tracking method, device, electronic device, and computer readable medium

The present disclosure provides a method, system, and terminal device for re-identifying a person in a closed place, relating to the field of video processing technologies. The method comprises: dividing a closed place into a plurality of regions comprising an entrance region, any of the regions comprising at least one camera for photographing; confirming a person first entering based on a trajectory tracking of the person in the entrance area, and assigning a unique identity number to the person, acquiring and recording feature information thereof and binding the identity number with the feature information; and when re-identification of a person in the closed place is performed, matching person's feature information captured by the camera of the region where the person is, with recorded feature information selecting the identity number bound with recorded feature information that best matches the feature information of the person as the identity number of the person.

A video image segmentation method includes: obtaining an image segmentation model by performing machine learning based on a historical video image and a mask image of the historical video image; adjusting the image segmentation model based on an initial frame of an image to be segmented, a previous frame of a frame to be segmented and a mask image of the previous image; and performing segmentation on the image to be segmented using the image segmentation model after the adjusting.

Video image segmentation method and apparatus, storage medium and electronic device

The disclosure relates to the technical field of data processing. Disclosed are a pedestrian flow funnel generation method and apparatus, a storage medium and an electronic device. The method can comprise: acquiring a current frame of image, and tracking and updating, according to a multi-target tracking algorithm, a head and shoulder area in a tracking sequence set in the current frame of image; acquiring, according to a head and shoulder recognition model, a head and shoulder area in the current frame of image, and updating, according to the head and shoulder area in the current frame of image, the tracking sequence set; analysing a motion track of each head and shoulder area in the tracking sequence set so as to count pedestrians, and when the current frame of image is the last frame of image, generating a pedestrian flow funnel based on a counting result of pedestrians.

Pedestrian flow funnel generation method and apparatus, storage medium and electronic device

A system and method for limiting access requests. In one system, a load balancer receives an access request, parses the access request into a UDP message, and transmits the UDP message to an aggregator; the aggregator accumulates the UDP message according to a predefined combination of data fields and a predefined duration so as to produce statistical data, and sends the statistical data to a summarizer in response to a request from the summarizer; the summarizer requests the statistical data from the aggregator according to a predefined request time interval, receives the statistical data from the aggregator, generates a blacklist for the access requests according to the received statistical data and a predefined rule, and sends the blacklist to the load balancer in response to a request from the load balancer. The load balancer determines a processing action on each of the received access requests according to the current blacklist.
