DR sign recognition device and method

The embodiment of the invention provides a DR sign recognition device and method, and the device comprises an image determining unit which is used for determining a to-be-recognized DR image; a sign recognition unit which is used for inputting the DR image into a sign recognition model to obtain a sign recognition result output by the sign recognition model; the sign recognition model which is used for determining a spatial distribution tensor and a classification prediction tensor of the DR image, and performing DR sign recognition based on a preset sign incidence matrix, the spatial distribution tensor and the classification prediction tensor. According to the device and the method provided by the embodiment of the invention, the DR sign recognition is carried out by combining the presetsign incidence matrix, the spatial distribution tensor and the classification prediction tensor, so a medically interpretable sign recognition result is obtained, and the reliability of sign recognition is improved. 本发明实施例提供
