Image-text matching aims to retrieve images from the guidance of textual queries or retrieve text expressions with the help of images. Existing Transformer-based methods compute attention for all tokens and thus suffer from redundant information, resulting in inadequate focus on salient features. On the other hand, the widely adopted bidirectional ranking loss overlooks the importance of expanding the distance between positive and negative samples, leading to the misclassification of negative samples as positive ones. In this work, we propose similarity shuffled criss-cross Transformer (SSCT) with angle loss for image-text matching. Specifically, a grouping-shuffling operation is introduced to better distinguish salient features from redundant information, bypassing the need for fully connected mapping. The grouping-shuffling operation establishes channel dependencies across different groups of feature representations, enhancing salient features while suppressing unimportant ones. Then, a criss-cross attention mechanism that equips self-attention with a novel criss-cross convolution is designed to make isolated information cooperatively express integral semantics. Moreover, a novel angle loss is introduced to expand the distances between positive and negative samples. Extensive experiments on the benchmark datasets of MSCOCO and Flickr30K demonstrate that the proposed methods achieve superior performances compared to state-of-the-art methods.

Abstract
Image-text matching aims to retrieve images from the guidance of textual queries or retrieve text expressions with the help of images. Existing Transformer-based methods compute attention for all tokens and thus suffer from redundant information, resulting in inadequate focus on salient features. On the other hand, the widely adopted bidirectional ranking loss overlooks the importance of expanding the distance between positive and negative samples, leading to the misclassification of negative samples as positive ones. In this work, we propose similarity shuffled criss-cross Transformer (SSCT) with angle loss for image-text matching. Specifically, a grouping-shuffling operation is introduced to better distinguish salient features from redundant information, bypassing the need for fully connected mapping. The grouping-shuffling operation establishes channel dependencies across different groups of feature representations, enhancing salient features while suppressing unimportant ones. Then, a criss-cross attention mechanism that equips self-attention with a novel criss-cross convolution is designed to make isolated information cooperatively express integral semantics. Moreover, a novel angle loss is introduced to expand the distances between positive and negative samples. Extensive experiments on the benchmark datasets of MSCOCO and Flickr30 K demonstrate that the proposed methods achieve superior performances compared to state-of-the-art methods.
