Problems solved by technology

However, since the existing feature extraction method only extracts features from the image based on a single convolution operation, the feature information of the target cannot be extracted well, which reduces the accuracy of feature extraction, thereby reducing the accuracy of target detection.

Abstract

The embodiment of the invention discloses a feature extraction method and device, computer equipment and a storage medium, and the method comprises the steps: sampling a preset neighborhood range from a to-be-processed image, obtaining at least one sampling region, and enabling the position points of the sampling region to comprise a sampling reference point and a plurality of neighborhood points; calculating a relative relationship between the sampling reference point and each neighborhood point in the sampling area; calculating a weight vector of each position point in the sampling area based on the relative relation; extracting a feature vector of each position point in the sampling area; calculating an output vector of the sampling area according to the weight vector and the feature vector of each position point in the sampling area; and generating a feature map corresponding to the to-be-processed image according to the output vector of each sampling region. According to the embodiment of the invention, the accuracy and convenience of feature extraction are improved.

Description

technical field [0001] The present application relates to the technical field of computer vision, and in particular, to a feature extraction method, apparatus, computer equipment and storage medium. Background technique [0002] With the continuous development of artificial intelligence, the target detection technology is becoming more and more mature, and its application is becoming more and more extensive. Among them, the target detection can be to find out the target of interest from the image, and determine the position of the target, etc. Feature extraction is an important step in the target detection process. At present, the existing feature extraction methods generally extract features from images through convolution operations, so as to predict the location of the target based on the features. However, since the existing feature extraction method only extracts features from images based on a single convolution operation, the feature information of the target cannot ...
