Abstract
An image recognition system includes a cloud server that stores a cloud recognition model and a local server that stores a local recognition model. The local server recognizes an image through the local recognition model to generate a local recognition result. The image corresponds to a field, the image includes at least one object, and the local recognition result includes local category confidence scores of each object corresponding to each of a plurality of categories. For each object, the local server calculates a local entropy indicator according to the field and the corresponding local category confidence scores. The local server determines to transmit the image to the cloud server according to the local entropy indicators of the image. The cloud server recognizes the image through the cloud recognition model to generate a cloud recognition result, and updates the local recognition model according to the cloud recognition result.
