Query: Dual-stream Network for Visual Recognition   Transformers with remarkable global representation capacities achieve
competitive results for visual tasks, but fail to consider high-level local
pattern information in input images. In this paper, we present a generic
Dual-stream Network (DS-Net) to fully explore the representation capacity of
local and global pattern features for image classification. Our DS-Net can
simultaneously calculate fine-grained and integrated features and efficiently
fuse them. Specifically, we propose an Intra-scale Propagation module to
process two different resolutions in each block and an Inter-Scale Alignment
module to perform information interaction across features at dual scales.
Besides, we also design a Dual-stream FPN (DS-FPN) to further enhance
contextual information for downstream dense predictions. Without bells and
whistles, the proposed DS-Net outperforms DeiT-Small by 2.4% in terms of top-1
accuracy on ImageNet-1k and achieves state-of-the-art performance over other
Vision Transformers and ResNets. For object detection and instance
segmentation, DS-Net-Small respectively outperforms ResNet-50 by 6.4% and 5.5%
in terms of mAP on MSCOCO 2017, and surpasses the previous state-of-the-art
scheme, which significantly demonstrates its potential to be a general backbone
in vision tasks. The code will be released soon.
