Convolutional neural networks （CNN） have been widely applied to image understanding, and they have arose much attention from researchers. Specifically, with the emergence of large image sets and the rapid development of GPUs, convolutional neural networks and their improvements have made breakthroughs in image understanding, bringing about wide applications into this area. This paper summarizes the up-to-date research and typical applications for convolutional neural networks in image understanding. We firstly review the theoretical basis, and then we present the recent advances and achievements in major areas of image understanding, such as image classification, object detection, face recognition, semantic image segmentation etc.
