Abstract: Convolutional Neural Network（CNN） has strong ability in finding characteristics of pictures. Recent years, with the arrival of big data era and the development of the computers, CNN has made great breakthrough in the field of image classification, object detection and so on. It has been widely studied in computer vision. This paper summarizes the theory of CNN, as well as the research and typical models on image classification, object detection. Finally, some existing problems in the CNN are analyzed, with forecasting the future development of CNN as well.

Key words: Convolutional Neural Network（CNN）, image classification, object detection
