Lesion image classification method based on convolutional neural network

Abstract

The invention relates to a focus area image classification method based on a convolutional neural network. The method specifically comprises the following steps: (1) collecting focus images to manufacture an image database, and marking the types of the images in the image database; (2) enhancing an original image in a training sample set by adopting an image enhancement algorithm to improve the texture and detail definition of the image; (3) constructing a lesion classification network, training the classification network by using the training sample set, and determining network parameters toobtain a classification model; and (4) inputting a lesion image to be tested into the lesion classification network to obtain the category to which the lesion belongs, and completing the classification of the lesion image. According to the method, global and color features and texture and detail features are extracted based on O-stream and P-stream models through the lesion classification networkdouble-stream CNN, and the final classification effect is effectively improved.

Description

technical field [0001] The invention relates to the processing field of lesion image classification, in particular to a method for classifying lesion images based on a convolutional neural network. Background technique [0002] In recent years, with the development of science and technology, endoscopic technology has been widely used clinically, which can achieve the purpose of observing the internal organs of the human body with the least damage. However, each endoscopy will generate a large number of data images. In order to detect lesion images, doctors need to spend a lot of time viewing images, and at the same time, missed and false detections may occur due to visual fatigue. Therefore, developing a set of methods for automatic classification of endoscopic lesion images is a key problem that needs to be solved urgently. At present, in the field of automatic detection of endoscopic lesion images, many researchers have adopted traditional machine learning methods, and t...
