From: Long-term reprojection loss for self-supervised monocular depth estimation in endoscopic surgery
Figure 1. Demonstration of back-projection and reprojection serves as two crucial steps in the view synthesis approach for depth and pose estimation with monocular endoscopy. Given camera intrinsics, the source image is projected onto the target image using predicted depth and pose. The reprojection loss then quantifies the dissimilarity between the target image and the reprojected image using L1 and SSIM losses.
