The embodiment of the present invention relates to the field of image recognition technology, and discloses a method, device, system, and storage medium for locating the fundus macula. The method includes: determining the optic disc area in the fundus image, at least one candidate macular area, and the corresponding confidence level; based on the optic disc area, determine the undetermined range of the macula; from at least one candidate macular area, screen out one or more candidate macular areas within the undetermined range of the macula; determine one or more candidate macular areas within the undetermined range of the macula The candidate macular region with the highest confidence in the region is the macular localization region. Through the image recognition model, the time-consuming is short, the applicability is good, and the work efficiency is high; the optic disc area is obtained through the image recognition model, and then based on the optic disc area, the accuracy of determining the macular location area is also greatly improved.
Description
technical field [0001] Embodiments of the present invention relate to the field of deep learning technology, and in particular to a method, device, system and storage medium for locating fundus and macula. Background technique [0002] The macula is an important physiological structure of the fundus and the optical center of the human eye. In fundus images, macular center localization is of great significance for the detection of diabetic retinopathy. The distance between the lesion area and the center of the macula determines the degree of impact on human vision and the severity of the lesion. Therefore, it is of great significance for macular localization. In traditional technologies, image processing methods are generally used to locate the macula, and the macula is located by features such as brightness and shape in the image or the positional relationship of physiological structures. These features will all be manually selected. The positioning of the macula depends...
