Show, Recall, and Tell: Image Captioning with Recall Mechanism

Understand

Generating natural and accurate descriptions in image cap-tioning has always been a challenge.

• In this paper, we pro-pose a novel recall mechanism to imitate the way human con-duct captioning.
• There are three parts in our recall mecha-nism : recall unit, semantic guide (SG) and recalled-wordslot (RWS).
• Recall unit is a text-retrieval module designedto retrieve recalled words for images.
