Patent ID: 10489909

Abstract:
A method of automatically detecting microaneurysm based on multi-sieving convolutional neural network (CNN), includes the following steps of: A1), partitioning an image to be detected using random fern and obtaining an auxiliary channel image of the image according to a first partition result; and A2), inputting the auxiliary channel image obtained from step A1) and the image to a multi-sieving CNN training model to perform a detection and obtaining a microaneurysm detection result of the image. The process of establishing the training model includes: B1), using a current microaneurysm diagnostic report as samples and partitioning a lesion image in the microaneurysm diagnostic report using the random fern, and establishing the auxiliary channel image according to a second partition result; B2), comparing the obtained auxiliary channel image with a lesion-marked image of pixels, clarifying the samples according to a comparing result and performing the multi-sieving CNN training.
