Oncomelania is a genus of very small tropical freshwater snails, aquatic gastropod mollusks in the family Pomatiopsidae. These Oncomelania snails are distantly related to the marine periwinkle, and more closely related to the small marine snails of the family Rissoidae.

A zero-shot Oncomelania snail identification method and system based on structured knowledge base and attention guidance

This invention relates to a zero-shot Oncomelania snail identification method and system based on a structured knowledge base and attention guidance, belonging to the field of image processing technology. The method includes: acquiring original images of Oncomelania snails; generating an attention map using a pre-trained model to locate and crop discriminative regions; constructing a structured Oncomelania snail knowledge base and guiding a large language model to generate fine-grained text descriptions; extracting image and text features separately, calculating region weights and text weights; and determining the snail species through weighted image-text similarity matching. This invention achieves zero-shot identification without annotating image data, effectively suppresses interference from complex backgrounds, significantly reduces data and annotation costs, and improves identification efficiency and robustness, making it suitable for low-cost Oncomelania snail monitoring in field environments.
