Problems solved by technology

Due to the capture of the same target, the number of images obtained is large, and the captured images are different in size, illumination, posture, occlusion, expression, etc., which makes it impossible to use a single image feature for image recognition. All parts of the image are recognized, and the effect of image recognition is poor

Abstract

The invention discloses a feature fusion method. The method comprises the steps of obtaining a plurality of images of a target object; inputting the plurality of images into a pre-trained image quality model to obtain the M-dimensional image quality of each image; inputting the plurality of images into a pre-trained feature recognition model to obtain N-dimensional image features of each image; performing weighted summation on the M-dimensional image quality and the N-dimensional image characteristics to obtain fusion characteristics, wherein M is a positive integer, N is a positive integer, when M is equal to 1, N is greater than or equal to 2, and when M is greater than or equal to 2, M is equal to N. The invention further provides a feature fusion device, an electronic device and a storage medium. According to the present invention, the image recognition effect can be improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a feature fusion method, device, electronic equipment and storage medium. Background technique [0002] In video recognition scenarios, multiple snapshots are usually taken for the same target, multiple images are obtained, and features are extracted from each image separately. Due to the capture of the same target, the number of images obtained is large, and the captured images are different in size, illumination, posture, occlusion, expression, etc., which makes it impossible to use a single image feature for image recognition. All parts of the image are recognized, and the effect of image recognition is poor. Contents of the invention [0003] In view of the above, it is necessary to provide a feature fusion method, device, electronic equipment and storage medium, which can improve the effect of image recognition. [0004] A first aspect of the present inv...
