Adaptive CNN-based Image Classification Algorithm Based on Deep Fusion of Multi-Feature

To improve the accuracy of image information extraction and image classification, an adaptive Convolutional Neural Network(CNN)-based algorithm is proposed for image classification.The algorithm effectively integrates the main color features of the image, and the spatial position features are extracted by using CNN.For the setting of the weight value of multi-features fusion, an improved differential evolution algorithm is presented to optimize the feature weight, so the accuracy of classification using fixed weight is improved.Experimental results show that the algorithm provides excellent image classification results, and its classification accuracy is 9.2% higher than that of CNN.
