Automatic Classification and Recognition of Spatiotemporal High-resolution Image Data Based on Deep Neural Networks
Abstract
Due to the huge volume of data obtained from spatiotemporal high-resolution images, traditional data classification methods cannot meet the requirements. This paper applied an automatic classification and recognition method to such data based on a deep convolutional neural network (DCNN). This method used the convolutional neural network (CNN) to extract the spatial and temporal features of the image, and combined the full connection layer for classification and recognition. Finally, the Softmax classifier was used to complete the classification of high-resolution images. For the experiments, 21 high-resolution remote sensing image (RS) datasets were selected as the research subjects. For the experimental analysis, the classification accuracy, precision, and recall of different classification algorithms were tested. Finally, the recognition rate of the neural network was adjusted by setting different expected errors. The data showed that the DCNN algorithm achieved a classification accuracy of 100% for the spatiotemporal high-resolution RS of shrubs and intersections, and the average precision and recall of DCNN were between 0.90 and 0.95, respectively. The image classification time after training was also the shortest, at 0.06ms. The experimental results show that for the classification and recognition of spatiotemporal high-resolution image data, the use of DCNN can achieve better performance and effect, and improve the efficiency
and accuracy of image classification.
