WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. WebIn the self-supervised loss formulation, a photometric reconstruction loss is employed during training. Although the self-supervised paradigm has evolved signiﬁcantly recently, the network outputs remain unscaled. This is because there is no metric information (e.g., from depth or pose labels) available during the training process. Herein, we ... how much postage required for 10x13Webevaluate a photometric reconstruction loss. Unlike [6], which uses a supervised pose loss and thus requires SE(3) labels for training, our self-supervised photometric loss obviates the need for this type of 6-DoF ground truth, which can often be arduous to obtain.
