Self-supervised Learning of Event-guided Video Frame Interpolation for Rolling Shutter Frames

no code implementations27 Jun 2023 Yunfan Lu, Guoqiang Liang, Lin Wang

Although events possess high temporal resolution, beneficial for video frame interpolation (VFI), a hurdle in tackling this task is the lack of paired GS frames.

Learning INR for Event-guided Rolling Shutter Frame Correction, Deblur, and Interpolation

1 code implementation24 May 2023 Yunfan Lu, Guoqiang Liang, Lin Wang

Images captured by rolling shutter (RS) cameras under fast camera motion often contain obvious image distortions and blur, which can be modeled as a row-wise combination of a sequence of global shutter (GS) frames within the exposure time naturally, recovering high-frame-rate GS sharp frames from an RS blur image needs to simultaneously consider RS correction, deblur, and frame interpolation Taking this task is nontrivial, and to our knowledge, no feasible solutions exist by far.

Deep Learning for Event-based Vision: A Comprehensive Survey and Benchmarks

1 code implementation17 Feb 2023 Xu Zheng, Yexin Liu, Yunfan Lu, Tongyan Hua, Tianbo Pan, Weiming Zhang, DaCheng Tao, Lin Wang

Event cameras are bio-inspired sensors that capture the per-pixel intensity changes asynchronously and produce event streams encoding the time, pixel position, and polarity (sign) of the intensity changes.

Ab Initio Particle-based Object Manipulation

no code implementations19 Jul 2021 Siwei Chen, Xiao Ma, Yunfan Lu, David Hsu

Like the model-based analytic approaches to manipulation, the particle representation enables the robot to reason about the object's geometry and dynamics in order to choose suitable manipulation actions.
