Abstract

The embodiment of the invention discloses a data enhancement method and device, a data processing method, electronic equipment and a computer storage medium. The method includes: selecting T image transformation manners from N image transformation manners, wherein N is an integer which is greater than 1, T is an integer which is greater than 0, and T<=N; and sequentially carrying out transformation processing, which corresponds to the T image transformation manners, on a current sample image to obtain a new sample image. According to the embodiment of the invention, image samples can be expanded, and a recognition accuracy degree of a network model obtained by training can be increased.

Description

technical field [0001] The invention belongs to the technical field of image preprocessing, and in particular relates to a sample image data enhancement method and device, a data processing method and device, electronic equipment and a computer storage medium. Background technique [0002] The image recognition technology based on machine learning obtains a network model with a wide range of recognition functions through the training of a large number of sample images. However, in the actual training process, the number of sample images of certain categories that can be collected is relatively rare and cannot Comprehensively reflect information in these categories. For example, for the same scene or object, there will be great differences in photos taken under different lighting, different angles or different cameras, and we can only collect photos taken under a certain lighting, a certain angle or a certain camera , as sample images to train the network model.
