IMAGE RECOGNITION METHOD AND DEVICE BASED ON DEEP CONVOLUTIONAL NEURAL NETWORK

摘要

The present invention relates to the technical field of medical treatment, in particular to an image recognition method and device based on a deep convolutional neural network. The method comprises the following steps: pre-processing chest X-ray films to obtain initial X-ray film images that meets format requirements; screening the initial X-ray film images to detect whether they are posteroanterior chest images; inputting the posteroanterior chest images into a binary classification model of the deep convolutional neural network for negative and positive classification; inputting the images presenting positive results into a detection model of the deep convolutional neural network to detect a disease type and label an outline of a lesion area in each image; and displaying the disease type and lesion area corresponding to the image. According to the image recognition method based on the deep convolutional neural network provided by this embodiment of the present invention, whether the chest X-ray films are negative or positive can be screened, the lesion areas can also be positioned, and meanwhile, the types or signs of the diseases in the lesion areas can be labeled to provide doctors with more interpretable reference opinions.
