Document Type and Number:
WIPO Patent Application WO/2020/006961
Kind Code:
A1
Abstract:
Embodiments of the present application disclose an image extraction method and device. A specific embodiment of the method comprises: acquiring a reference object image and a set of images to be matched; and inputting the reference object image into a first sub network comprised in a pre-trained image recognition model, and acquiring a feature vector of the reference object image as a reference feature vector, wherein the following extraction steps are executed on images to be matched in the set of images to be matched: inputting the image to be matched into a second sub network comprised in the image recognition model, so as to acquire at least one piece of position information and a feature vector to be matched corresponding to the position information; determining the distance between the acquired feature vector to be matched and the reference feature vector; and in response to determining that the determined distances comprise a distance less than or equal to a preset distance threshold, extracting the image to be matched as an image matching the reference object image. The embodiments improve the flexibility of image recognition, and enrich the means of image recognition.
