WebMar 17, 2024 · The first two are defined for single images and the photometric reconstruction loss relies on temporal photo-consistency for three consecutive frames (Fig. 2). The total loss is the weighted sum of the single image loss for each frame and the reconstruction loss
WebOur framework instead leverages photometric consistency between multiple views as supervisory signal for learning depth prediction in a wide baseline MVS setup. However, … 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 ...
WebApr 24, 2024 · We find the standard reconstruction metrics used for training (landmark reprojection error, photometric error, and face recognition loss) are insufficient to capture high-fidelity expressions. The result is facial geometries that do not match the emotional content of the input image. We address this with EMOCA (EMOtion Capture and …
