Vanishing Depth: Training Generalized Depth Adapters with Sinusoidal Depth Preprocessing for Pretrained RGB Encoders
Researchers have developed a novel self-supervised training method to equip pretrained RGB encoders with generalized metric depth understanding. This approach introduces a depth adapter that integrates metric depth information into a combined latent space without disrupting the existing RGB features. The method, enhanced by sinusoidal depth encoding, allows for robust depth-invariant feature extraction and improves performance across various downstream tasks like segmentation and pose estimation, even when depth data is sparse or absent.
