4 results about "Point correspondence" patented technology

Point-to-point correspondence is a relationship between a discriminative stimulus and the response it controls. In point-to-point correspondence, both the discriminative stimulus and the response must have two or more components.

Systems and methods for performing self-improving visual odometry

ActiveUS12650598B2Image enhancementImage analysisPattern recognitionThree-dimensional space
In an example method of training a neural network for performing visual odometry, the neural network receives a plurality of images of an environment, determines, for each image, a respective set of interest points and a respective descriptor, and determines a correspondence between the plurality of images. Determining the correspondence includes determining one or point correspondences between the sets of interest points, and determining a set of candidate interest points based on the one or more point correspondences, each candidate interest point indicating a respective feature in the environment in three-dimensional space). The neural network determines, for each candidate interest point, a respective stability metric and a respective stability metric. The neural network is modified based on the one or more candidate interest points.

A point recommendation method, device and electronic device

ActiveCN119557508BDigital data information retrievalForecastingSimulationPoint correspondence
Embodiments of the present invention disclose a point recommendation method, apparatus, and electronic device. By obtaining a target location, in response to the target location being a low-heat location, obtaining the boarding and alighting data and trajectory information corresponding to the target location, recalling at least one recommended point based on the boarding and alighting data and trajectory information of the target location, and controlling the point recall page of the user terminal to display at least one of the recommended points. Thus, when the target location is a low-heat location with insufficient historical data, the boarding and alighting points can be used interchangeably in the embodiments of the present invention, and the trajectory information is used as supplementary information for point recall, enriching the number of recallable points, improving the accuracy of point recommendation for low-heat locations, and further improving the user experience.

Point recommendation method and device, electronic equipment and storage medium

ActiveCN116401443BDigital data information retrievalEnergy efficient computingEngineeringImage pair
This invention discloses a point-of-interest recommendation method, apparatus, electronic device, and storage medium. The method includes: acquiring a user's current captured image information; comparing the user's captured image with multiple file information in a reference file set to determine the target file information corresponding to the user's captured image; determining a corresponding trip frequency matrix based on the target file information and the current point-of-interest information; the target file information includes captured image information of the user at multiple trip points, and the trip frequency matrix describes the number of times the user appears at each trip point at different times, with pre-calculated distance similarity and time similarity between multiple trip points; determining target interest points based on the trip frequency matrix, and recommending points of interest based on the target interest points. This makes the point-of-interest recommendation significantly more reasonable, capable of addressing user interest needs at different times and locations, and improving the accuracy and recall of the recommendation.
