DISTWAR: Fast Differentiable Rendering on Raster-based Rendering Pipelines

no code implementations1 Dec 2023 Sankeerth Durvasula, Adrian Zhao, Fan Chen, Ruofan Liang, Pawan Kumar Sanjaya, Nandita Vijaykumar

In this work, we observe that the gradient computation phase during training is a significant bottleneck on GPUs due to the large number of atomic operations that need to be processed.

ENVIDR: Implicit Differentiable Renderer with Neural Environment Lighting

1 code implementation ICCV 2023 Ruofan Liang, Huiting Chen, Chunlin Li, Fan Chen, Selvakumar Panneer, Nandita Vijaykumar

In this work, we introduce ENVIDR, a rendering and modeling framework for high-quality rendering and reconstruction of surfaces with challenging specular reflections.

EvConv: Fast CNN Inference on Event Camera Inputs For High-Speed Robot Perception

no code implementations8 Mar 2023 Sankeerth Durvasula, Yushi Guan, Nandita Vijaykumar

We also demonstrate a speedup of up to 1. 6X for inference using CNNs for tasks such as depth estimation, object recognition, and optical flow estimation, with almost no loss in accuracy.

SPIDR: SDF-based Neural Point Fields for Illumination and Deformation

no code implementations15 Oct 2022 Ruofan Liang, Jiahao Zhang, Haoda Li, Chen Yang, Yushi Guan, Nandita Vijaykumar

To enable more accurate illumination updates after deformation, we use the shadow mapping technique to approximate the light visibility updates caused by geometry editing.

Echo: Compiler-based GPU Memory Footprint Reduction for LSTM RNN Training

no code implementations22 May 2018 Bojian Zheng, Abhishek Tiwari, Nandita Vijaykumar, Gennady Pekhimenko

For each feature map recomputation to be effective and efficient, its effect on (1) the total memory footprint, and (2) the total execution time has to be carefully estimated.
