InkSight: Offline-to-Online Handwriting Conversion by Learning to Read and Write

no code implementations8 Feb 2024 Blagoj Mitrevski, Arina Rak, Julian Schnitzler, Chengkun Li, Andrii Maksai, Jesse Berent, Claudiu Musat

Our work, InkSight, aims to bridge the gap by empowering physical note-takers to effortlessly convert their work (offline handwriting) to digital ink (online handwriting), a process we refer to as Derendering.

Understanding Pixel-level 2D Image Semantics with 3D Keypoint Knowledge Engine

no code implementations21 Nov 2021 Yang You, Chengkun Li, Yujing Lou, Zhoujun Cheng, Liangwei Li, Lizhuang Ma, Weiming Wang, Cewu Lu

Pixel-level 2D object semantic understanding is an important topic in computer vision and could help machine deeply understand objects (e. g. functionality and affordance) in our daily life.

Are We Hungry for 3D LiDAR Data for Semantic Segmentation? A Survey and Experimental Study

no code implementations8 Jun 2020 Biao Gao, Yancheng Pan, Chengkun Li, Sibo Geng, Huijing Zhao

Finally, a systematic survey to the existing efforts to solve the data hunger problem is conducted on both methodological and dataset's viewpoints, followed by an insightful discussion of remaining problems and open questions To the best of our knowledge, this is the first work to analyze the data hunger problem for 3D semantic segmentation using deep learning techniques that are addressed in the literature review, statistical analysis, and cross-dataset and cross-algorithm experiments.
