Automatically generating captions of an image is a task near to the core of scene understanding which is one of the essential objectives of computer vision. To achieve the objective of image captioning, semantic information of images should be caught and described in natural language. Image captioning is a very difficult undertaking, because it requires interfacing both research areas of NLP (natural language processing) and computer vision. There have been introduced several techniques for image captioning. The recent development in the image captioning is based on the advancement of artificial intelligence. This paper gives a review on some of the milestones in the field of automatic image captioning and provides comparison of methods based on some major evaluation metrics.
