摘要
Image super-resolution (SR) is an important technique for improving the resolution and quality of images. With the great progress of deep learning, image super-resolution achieves remarkable improvements recently. In this work, a brief survey on recent advances of deep learning based single image super-resolution methods is systematically described. The existing studies of SR techniques are roughly grouped into ten major categories. Besides, some other important issues are also introduced, such as publicly available benchmark datasets and performance evaluation metrics. Finally, this survey is concluded by highlighting four future trends. Copyright © by HIGH TECHNOLOGY LETTERS PRESS.
