These mechanisms improve performance by learning to focus on the regions of the image that are salient and are currently based on deep neural network architectures. Abstract: Attention mechanisms have been extensively adopted in vision and language tasks such as image captioning. The main difficulties originate from two aspect: (1) The noise and complex background information in the image are likely to interfere with the generation of correct caption; (2) The relationship between features in the image is often overlooked. In: IEEE Conference on Computer Vision . Attention is generated out of dense nueral network layers to capture the weights of the encoder features and get the focus on that part of the image which needs a caption. Existing attention based approaches treat local feature and global feature in the image individually, neglecting the intrinsic interaction between them that provides important guidance for generating caption.
