The matching relationship between the target objects.
- the two feature descriptors of the to-be-processed picture are a first feature descriptor and a second feature descriptor, respectively, and the first feature descriptor is first European between the feature descriptors of the source image.
- the distance is greater than a second Euclidean distance between the second feature descriptor and a feature descriptor of the source picture.
- the specified feature descriptor is a feature descriptor of the target object in the source picture.
- the step S303 may be specifically: when the ratio of the second Euclidean distance to the first Euclidean distance is less than a preset value, determining that the to-be-processed picture matches the source picture.
- the preset value may be a value greater than 0.6 and less than 0.9. More specifically, the preset value may be a value greater than 0.6 and less than 0.7.
- Step S103 Publish the to-be-processed picture whose matching degree is greater than the threshold as the target picture.
- the to-be-processed picture with the matching degree of the source picture that is greater than the threshold may be put into the target picture set, and after each picture to be processed is matched with the source picture, each target in the target picture set is obtained.
- the image is published to generate image information of the target object.
- the target picture is a to-be-processed picture whose matching degree with the source picture is greater than a threshold.
- the image matching method obtains the shape feature information and the tone feature information of the target object in the source image, and generates a feature descriptor that represents the shape feature information and the tone feature information of the target object, and according to the feature descriptor, the target file
- a feature descriptor that represents the shape feature information and the tone feature information of the target object
- the target file Each of the to-be-processed pictures included in the folder is matched with the source picture, and finally the to-be-processed picture whose matching degree is greater than the threshold is released as the target picture, thereby reducing the time required for selecting all the pictures of the target object one by one.
