Abstract

The invention provides a target detection method, an electronic device and a storage medium, a target image is identified through a pre-trained fine-grained target detection model, and the training process of the pre-trained fine-grained target detection model is obtained by retraining a preset target detection model based on an interval loss function. the interval loss function is determined based on the learning interval between the preset fine-grained categories and the loss function of the preset target detection model, and the learning interval between the preset fine-grained categories enables the loss function of the preset target detection model not to pursue learning of the difference characteristics of each instance in the training sample in the model retraining process; therefore, the model complexity of the preset target detection model in the retraining process is not higher than that of an actual model. Therefore, an over-fitting phenomenon in a fine-grained recognition scene can be effectively avoided, and the accuracy of target detection can be improved.

Description

technical field [0001] The present application relates to the technical field of target detection, and in particular, to a target detection method, an electronic device and a storage medium. Background technique [0002] Common object detection is divided into coarse-grained object detection and fine-grained object detection. Among them, coarse-grained object detection refers to the detection of objects in different categories, while fine-grained object detection refers to the detection of different instances within the same category. For example, the detection of different categories of animals such as cats, dogs, and birds is coarse-grained object detection, while the detection of different instances within the same animal category, such as dog categories, such as border collies, poodles, huskies, etc., is fine-grained Target Detection. At present, in fine-grained target detection, due to the overfitting between non-background features in training samples, the accuracy o...
