Cache Me if You Can: Accelerating Diffusion Models through Block Caching

CVPR 2024poster

Diffusion models have recently revolutionized the field of image synthesis due to their ability to generate photorealistic images. However one of the major drawbacks of diffusion models is that the image generation process is costly. A large image-to-image network has to be applied many times to ite…

ControlRoom3D: Room Generation using Semantic Proxy Rooms

CVPR 2024poster

Manually creating 3D environments for AR/VR applications is a complex process requiring expert knowledge in 3D modeling software. Pioneering works facilitate this process by generating room meshes conditioned on textual style descriptions. Yet many of these automatically generated 3D meshes do not a…

A Practical Stereo Depth System for Smart Glasses

CVPR 2023poster

We present the design of a productionized end-to-end stereo depth sensing system that does pre-processing, online stereo rectification, and stereo depth estimation with a fallback to monocular depth estimation when rectification is unreliable. The output of our depth sensing system is then used in a…

NeRF-Det: Learning Geometry-Aware Volumetric Representation for Multi-View 3D Object Detection

ICCV 2023poster

We present NeRF-Det, a novel method for indoor 3D detection with posed RGB images as input. Unlike existing indoor 3D detection methods that struggle to model scene geometry, our method makes novel use of NeRF in an end-to-end manner to explicitly estimate 3D geometry, thereby improving 3D detection…

Efficient Segmentation: Learning Downsampling Near Semantic Boundaries

ICCV 2019poster

Many automated processes such as auto-piloting rely on a good semantic segmentation as a critical component. To speed up performance, it is common to downsample the input frame. However, this comes at the cost of missed small objects and reduced accuracy at semantic boundaries. To address this probl…
