Abstract: Image recognition is one of the core research directions in the field of computer vision research, which can be divided into general image recognition and fine‐grained image recognition. General image recognition refers to the recognition of different types of objects; fine‐grained image recognition refers to the recognition of different subclasses in the same broad class of objects, such as SME financing inventory pledge image recognition. In this paper, we propose a partial differential equation‐based image recognition method for SME financing inventory pledges and conduct detailed analysis and experiments. Compared with general images, partial differential equation‐based SME financing inventory pledges image recognition is difficult to recognize due to data characteristics such as small differences in features between classes, large differences in features within classes, and a small percentage of targets in the image. To address the problem that existing methods ignore the role of shallow features on fine‐grained image recognition, this paper proposes a fine‐grained image recognition method based on partial differential equations. By analyzing the important role of shallow features for fine‐grained image recognition, a feature fusion method with adaptive weights is proposed. Using this method to fuse shallow and high‐level semantic features for recognition, the role of shallow features in fine‐grained image recognition is fully exploited. In addition, the proposed method does not change the order of magnitude of the model parameters and is highly transferable. The relevant experimental results verify the effectiveness of the proposed method.
