基于多模态特征融合与动态注意力机制的目标识别算法
An Object Recognition Algorithm Based on Multi-modal Feature Fusion and Dynamic Attention Mechanism
摘要
Abstract
Aiming at the problem that single-modal object recognition is easily affected by climate and interference,an object recogni-tion algorithm based on multi-modal image feature fusion is proposed.The proposed method is divided into the following four primary steps.In the first step,multi-modal images are preprocessed,during which the visible light,infrared,and SAR images of the ground scene are augmented respectively based on their modality-specific characteristics to enhance the model's generalization ability and ro-bustness.Next,corresponding classification labels are assigned to each image.Subsequently,different deep learning networks are designed to train data with different modalities separately,and the classification heads of all pre-trained networks are then removed.Finally,each classification network is connected to the feature fusion module for a retraining,so as to improve the classification accu-racy of the object classification.The method proposed in this paper accomplishes information complementation by employing multi-modal image feature fusion for object recognition,thereby achieving efficient identification of space objects.Experimental results demonstrate that the proposed algorithm achieves a high recognition accuracy of 96.74%on the WHU-OPT-SAR dataset.关键词
