Photometric reprojection loss
WebFeb 28, 2024 · Next, a photometric reprojection loss estimates the full 6 DoF motion using a depth map generated from the decoupled optical flow. This minimization strategy enables our network to be optimized without using any labeled training data. To confirm the effectiveness of our proposed approach (SelfSphNet), several experiments to estimate … WebBesides, we integrate the gradients of the image into the photometric reprojection loss to handle the confusion caused by changing brightness. We conduct experiments on KITTI datasets and show that our network achieves the state-of-art result. Published in: 2024 ...
