Embodiment Construction

[0047] In the following detailed description, numerous specific details of the disclosure are set forth by way of example in order to provide a thorough understanding of the relevant disclosure. It will be apparent, however, to one of ordinary skill in the art that the present disclosure may be practiced without these details. It should be understood that the terms "system", "device", "unit" and / or "module" used in the present disclosure are used as a means of distinguishing between different parts, elements, sections or assemblies at different levels in a sequential arrangement. method. However, these terms may be replaced by other expressions if the same purpose can be achieved by other expressions.

[0048]It will be understood that when a device, unit or module is referred to as being "on," "connected to" or "coupled to" another device, unit or module, it can be directly on the other device, unit or module. connected or coupled to or communicate with other devices, units...

Abstract

The embodiment of the present disclosure discloses a convolutional neural network migration method. Wherein, the method includes: improving the last pooling layer of the first convolutional neural network to obtain a second convolutional neural network, so that the resolution of the input image of the second convolutional neural network is greater than that of the first convolutional neural network. The resolution of the input image for the convolutional neural network. This method is applicable to input datasets of different sizes, such as high-resolution fundus images, and saves the computational resources consumed by developing dedicated convolutional neural networks.

Description

technical field [0001] The present disclosure relates to the field of medical image processing, in particular to a fundus image screening method, device, electronic equipment and storage medium. Background technique [0002] With the breakthrough of artificial intelligence technology, the application of new artificial intelligence in the field of medical image processing, especially the machine learning method based on massive data, is becoming an emerging research and application hotspot. Among them, the automatic identification of diabetic retinopathy is a rapidly emerging branch. [0003] When using fundus images of patients for Diabetic retinopathy (Diabetic retinopathy, DR) screening, no matter through manual or automated methods, it is necessary to determine whether the patient has received laser photocoagulation before, because whether laser photocoagulation has been received Surgical treatment will affect the classification of DR in subsequent screening. Laser spot ...
