DTFormer: Text-Guided Semantic Alignment for RGB-D Segmentation

RGB-D semantic segmentation has made notable progress by fusing RGB and Depth, yet mainstream models still learn features almost exclusively from pixel-level supervision, lacking direct high-level semantic constraints. This raises a central question-can external knowledge such as language priors inject stronger semanti...

Efficient and Robust Absolute Pose Estimation via Gravity-Prior-Driven Transformation Decoupling and Pose Refinement

A novel transformation strategy that exploits geometric relations derived from the gravity prior is proposed that achieves stronger performance compared to existing state-of-the-art (SOTA) approaches and is integrated into ORB-SLAM2.
