Figure 1. Comparisons among the main RGBD segmentation pipelines and our approach. (a) Use dual encoders to encode RGB and depth respectively and design fusion modules to fusion them [28, 61]; (b) Adopt an unified RGBD encoder to extract and fuseRGBDfeatures[1,59]; (c)OurDFormerv2usedepthtoform ageometrypriorofthesceneandthenenhancethevisualfeatures.
