Learning Event Guided High Dynamic Range Video Reconstruction
Computer Vision and Pattern Recognition, 2023Limited by the trade-off between frame rate and exposure time when capturing moving scenes with conventional cameras, frame based HDR video reconstruction suffers from scene-dependent exposure ratio balancing and ghosting artifacts. Event cameras provide

RawHDR: High Dynamic Range Image Reconstruction from a Single Raw Image
IEEE International Conference on Computer Vision, 2023High dynamic range (HDR) images capture much more intensity levels than standard ones. Current methods predominantly generate HDR images from 8-bit low dynamic range (LDR) sRGB images that have been degraded by the camera processing pipeline. However, it

Learning to Reconstruct High Speed and High Dynamic Range Videos from Events
Computer Vision and Pattern Recognition, 2021Event cameras are novel sensors that capture the dynamics of a scene asynchronously. Such cameras record event streams with much shorter response latency than images captured by conventional cameras, and are also highly sensitive to intensity change ...

Neural Auto-Exposure for High-Dynamic Range Object Detection
Computer Vision and Pattern Recognition, 2021Real-world scenes have a dynamic range of up to 280 dB that todays imaging sensors cannot directly capture. Existing live vision pipelines tackle this fundamental challenge by relying on high dynamic range (HDR) sensors that try to recover HDR images ...

Neuromorphic Camera Guided High Dynamic Range Imaging
Computer Vision and Pattern Recognition, 2020Reconstruction of high dynamic range image from a single low dynamic range image captured by a frame-based conventional camera, which suffers from over- or under-exposure, is an ill-posed problem.

End-to-end High Dynamic Range Camera Pipeline Optimization
Computer Vision and Pattern Recognition, 2021The real world is a 280 dB High Dynamic Range (HDR) world which imaging sensors cannot record in a single shot. HDR cameras acquire multiple measurements with different exposures, gains and photodiodes, from which an Image Signal Processor (ISP ...
