Abstract

The invention provides a multi-feature fusion method and device, electronic equipment and a storage medium. The multi-feature fusion method comprises the steps of obtaining a plurality of nonlinear features in an image data pair of a target object; inputting each nonlinear feature into a preset multi-kernel function to obtain a feature weight value corresponding to each nonlinear feature; and obtaining the fusion feature of each nonlinear feature according to the weighted sum of each feature weight value and the kernel function corresponding to each nonlinear feature. According to the fusion features obtained by the invention, multiple features can be mapped to a nonlinear feature projection space, the optimal combination of the multiple features is realized, and the calculation complexityof big data is simplified.

Description

technical field [0001] The embodiment of the present application relates to the technical field of one-time identification, and in particular relates to a multi-feature fusion method, device, electronic equipment, and storage medium. Background technique [0002] Recently, human identification has received extensive attention in the field of computer vision, and human identification is one of the important tasks in large-scale camera networks (such as large-scale surveillance camera networks). It has several potential applications, including real-time human detection in noisy and crowded spaces such as shopping malls, or in e-commerce, or on subway / bus stations, or in crowded public areas such as airports and parks. Identity tracking for public safety, for example, in one-off identification applications where street or outdoor surveillance cameras capture suspects outdoors. [0003] In the related art, in the one-time recognition technology used for human identity recogniti...
