Abstract

The embodiment of the invention provides a method and a device for determining a feature value of an image, a storage medium and an electronic device. The method comprises the following steps: extracting a feature vector of an obtained target image; determining the similarity between the feature vector of the target image and the feature vector in the first feature vector set; adjusting the similarity to obtain the target similarity of the feature vector of the target image; and determining a feature value of the target image based on the target similarity. Through the method and the device, the problem of low matching degree of the tensile fitting function and the sample caused by contingency of random sampling in related technologies is solved, and the effect of the matching degree of the tensile fitting function and the sample is achieved.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and in particular, relate to a method and device for determining feature values ​​of an image, a storage medium, and an electronic device. Background technique [0002] Usually, the image search technology is realized by calculating the similarity of feature vectors through feature comparison. The calculation of the similarity of eigenvectors is usually by calculating the distance between two eigenvectors. The commonly used distance calculation methods usually include: Euclidean distance, cosine distance, Hamming distance, Jaccard similarity coefficient, etc. [0003] In the execution method of specific retrieval, a variety of methods have been introduced, including but not limited to (K-NearestNeighbor, referred to as KNN, the algorithm represents the vector of accurate recall topK), (Approximate NearestNeighbor, referred to as ANN, algorithm Represents the approximate K proximi...
