DOI: 10.1109/lra.2023.3240646
Abstract: Estimating neural radiance fields (NeRFs) from “ideal” images has been extensively studied in the computer vision community. Most approaches assume optimal illumination and slow camera motion. These assumptions are often violated in robotic applications, where… read more here.

DOI: 10.1109/lra.2023.3259731
Abstract: Event cameras capture visual information with a high temporal resolution and a wide dynamic range. This enables capturing visual information at fine time granularities (e.g., microseconds) in rapidly changing environments. This makes event cameras highly… read more here.

DOI: 10.1109/lsp.2022.3196599
Abstract: The letter introduces an efficient context-based lossless image codec for encoding event camera frames. The asynchronous events acquired by an event camera in a spatio-temporal neighborhood are collected by an Event Frame (EF). A more… read more here.

DOI: 10.1109/tpami.2021.3096985
Abstract: An event camera reports per-pixel intensity differences as an asynchronous stream of events with low latency, high dynamic range (HDR), and low power consumption. This stream of sparse/dense events limits the direct use of well-known… read more here.

DOI: 10.1109/tpami.2022.3152999
Abstract: Dynamic Vision Sensor (DVS) event camera output includes uninformative background activity (BA) noise events that increase dramatically under dim lighting. Existing denoising algorithms are not effective under these high noise conditions. Furthermore, it is difficult… read more here.

DOI: 10.1364/oe.482348
Abstract: Multipath in 3D imaging happens when one pixel receives light from multiple reflections, which causes errors in the measured point cloud. In this paper, we propose the soft epipolar 3D(SEpi-3D) method to eliminate multipath in… read more here.
