1 code implementation • 12 Mar 2024 • Chunlong Xia, Xinliang Wang, Feng Lv, Xin Hao, Yifeng Shi

Compared to the state-of-the-art, ViT-CoMer has the following advantages: (1) We inject spatial pyramid multi-receptive field convolutional features into the ViT architecture, which effectively alleviates the problems of limited local information interaction and single-feature representation in ViT.
