Photometric reconstruction loss
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 ... WebWe use three types of loss functions; supervision on image reconstruction L image , supervision on depth estimation L depth , and photometric loss [53], [73] L photo . The …

WebApr 28, 2024 · We then apply a self-supervised photometric loss that relies on the visual consistency between nearby images. We achieve state-of-the-art results on 3D hand-object reconstruction benchmarks and demonstrate that our approach allows us to improve the pose estimation accuracy by leveraging information from neighboring frames in low-data … WebJun 20, 2024 · Building on the supervised optical flow CNNs (FlowNet and FlowNet 2.0), Meister et al. replace the supervision of synthetic data with an unsupervised photometric reconstruction loss. The authors compute bidirectional optical flow by exchanging the input images and designing a loss function leveraging bidirectional flow.
