Abstract
For one-shot segmentation, prototype learning is extensively used. However, using only one RGB prototype to represent all information in the support image may lead to ambiguities. To this end, we propose a one-shot segmentation network based on multi-modal prototype learning that uses depth information to complement RGB information. Specifically, we propose a multi-modal fusion and refinement block (MFRB) and multi-modal prototype learning block (MPLB). MFRB fuses RGB and depth features to generate multi-modal features and refined depth features, which are used by MPLB, to generate multi-modal information prototypes, depth information prototypes, and global information prototypes. Furthermore, we introduce self-attention to capture global context information in RGB and depth images. By integrating self-attention, MFRB, and MPLB, we propose the multi-modal prototype learning network (MMPL-Net), which adapts to the ambiguity of visual information in the scene. Finally, we construct a one-shot RGB-D segmentation dataset called OSS-RGB-D-5i. Experiments using OSS-RGB-D-5i show that our proposed method outperforms several state-of-the-art techniques with fewer labeled images and generalizes well to previously unseen objects.
