Abstract

The present application provides a recognition method and a system for pathological images. The recognition system comprises an image receiving device used for receiving a to-be-recognized pathological image; a feature extracting device used for extracting the features of the pathological image by utilizing multiple stages of feature processing units arranged in a convolutional neural network; anda recognition device used for conducting the fusion treatment on feature images outputted by at least two stages of feature processing units and then recognizing the pathological information in the pathological image based on the pathological features of fused images. According to the invention, low-dimensional and high-dimensional pathological features are effectively retained, so that lesion features can be accurately recognized. Meanwhile, the lesion features are accurately mapped to the pixel positions of the pathological image, so that the auxiliary diagnosis accuracy is improved.

Description

technical field [0001] The present application relates to the field of computer processing technology, in particular to a pathological image recognition method and system. Background technique [0002] A pathological image is an image obtained by slicing the tissue of the patient's lesion and magnifying it under a microscope. Pathological images can reveal the cause and severity of diseases, and are an important means of clinical diagnosis. With the increase in the number of patients and the shortage of professional pathologists, computer-aided pathological image recognition has become an important development direction. [0003] A known computer-aided detection technique uses pathological features to identify pathological images. For example, the pathological feature matrix is ​​used to filter the pathological image by convolution, and then a classification algorithm is used to classify the filtered pathological feature image as having lesion information or not having les...
