Abstract: For the problem of melanoma image diagnosis, this paper proposes a recognition method based on a deformable partition attention mechanism. This method adopts a coarse-to-fine feature extraction and recognition strategy to accurately distinguish melanoma from common moles and establish corresponding semantic labels. Based on this, a multimodal dermatological corpus is constructed by integrating case texts. First, to tackle issues such as blurred lesion boundaries, uneven distribution, and difficulty in feature extraction, this paper introduces a deformable partition attention module that combines attention mechanisms with deformable convolutions. Second, to address the large differences between benign and malignant subcategories that result in training difficulties and low recognition efficiency, this paper constructs a hierarchical learning framework that progresses from coarse to fine categories. In addition, a joint loss function is introduced to optimize the model’s recognition accuracy. Experimental results show that the proposed algorithm demonstrates high sensitivity and specificity on self-constructed dataset, effectively improving the accuracy of multimodal dermatological corpus construction by matching case texts with medical images.
