- W4386137987 abstract "Abstract Unsupervised 2D image-based 3D model retrieval aims at retrieving images from the gallery of 3D models by the given 2D images. Despite the encouraging progress made in this task, there are still two significant limitations: (1) feature alignment of 2D images and 3D model gallery is still difficult due to the huge gap between the two modalities. (2) The important view information in the 3D model gallery was ignored by the prior arts, which led to inaccurate results. To alleviate these limitations, inspired by the success of vision transformers (ViT) in a great variety of vision tasks, in this paper, we propose an end-to-end 3D model retrieval architecture on top of ViT, termly transformer-based 3D model retrieval network (T3DRN). In addition, to take advantage of the valuable view information of 3D models, we present an attentive module in T3DRN named shared view-guided attentive module (SVAM) to guide the learning of the alignment features. The proposed method is tested on the challenging dataset, MI3DOR-1. The extensive experimental results have proved the superiority of our proposed method to state-of-the-art methods." @default.
