Figure 1. Given an LDR panorama (a), we estimate geometry (b-c), SV illumination and SVBRDFs, including base color (d), roughness (e) and metalness (f). Our physics-based differentiable renderer can produce detailed specular reflectance (g) on complex material. Based on such physical cons...
In this paper, spectral variation is considered from a physics-based approach and incorporated into an end-to-end spectral unmixing algorithm via differentiable programming. The dispersion model is introduced to simulate realistic spectral variation, and an efficient method to fit the parameters is ...

Our OSC implementation is fully differentiable in Isaac Gym and we obtain convergence with this controller in under 25 minutes. Figure 12 shows the training results. 6.4 Robotic Hands Figure 13: The three in-hand manipulation environments implemented in Isaac Gym: Shadow Hand, Trifinger, and ...
Our contribution consists of a novel methodology for retrieving a continuous echogenicity map directly from a B-mode image through a differentiable physics-based rendering pipeline for ultrasound resolution enhancement. We qualitatively and quantitatively evaluate our approach on synthetic data, demonstrating ...
