Description

technical field [0001] The invention relates to the field of automatic recognition and classification of medical microscope images by using a computer vision scheme, in particular to a method and system for automatic recognition of human cell proteins based on a convolutional neural network. Background technique [0002] The convolutional neural network can learn the spatial features in the original data, and a feature representation learner can be formed by stacking different convolutional layers together. The learner learns the feature representation of the input data layer by layer from shallow to deep, and finally outputs a low-dimensional feature vector relative to the original data, which can be used as an input feature by the classifier to achieve correct classification of the original data. The convolutional neural network and the fully connected classifier are spliced ​​together to form a common convolutional neural network classifier, and the convolution kernel wei...
