Recognition algorithm of marine single-cell algae based on deep learning VGG network

In order to better identify marine single-celled algae,a single-cell alga recognition algorithm is developed based on improved VGG16 network—AlgaeNet.This algorithm is derived from the traditional VGG network,reducing the number of convolution kernels,and adding BatchNormalization layer to accelerate the neural network.The convergence rate of the loss value during the training process and the increase rate of the prediction accuracy of the test set samples(Chlorella ovalis and Dictyocha fibula Ehrenberg)are found to be better under the same experimental conditions,compared with the traditional VGG network and the AlexNet network,with prediction accuracy of 99.317%.Experimental results showed that the algorithm had better classification and recognition performance in the field of single-celled alga recognition,with accurate recognition of marine single-celled algae.
