--Apologize for multiple emails. CFP: SHREC'19 Tracks on Extended 3D Scene Retrieval Dear Colleagues, This is to invite you to participate in the following two 2019 Shape Retrieval Contest (SHREC) tracks: (1) SHREC'19 Track: Extended 2D Scene Sketch-Based 3D Scene Retrieval URL: http://orca.st.usm.edu/~bli/SceneSBR2019/index.html Contact: Juefei Yuan: Juefei.yuan(a)usm.edu <mailto:Juefei.yuan@usm.edu> (2) SHREC'19 Track: Extended 2D Scene Image-Based 3D Scene Retrieval URL: http://orca.st.usm.edu/~bli/SceneIBR2019/index.html Contact: Hameed Abdul-Rashid: hameed.abdulrashid(a)usm.edu <mailto:hameed.abdulrashid@usm.edu> which will be held in conjunction with the 12th EUROGRAPHICS Workshop on 3D Object Retrieval (3DOR'19), May 5-6, 2019, Genova, Italy (http://3dor2019.ge.imati.cnr.it/). In the months following our SHREC'18 2D Scene Sketch-Based 3D Scene Retrieval (SceneSBR2018) and 2D Scene Image-Based 3D Scene Retrieval (SceneIBR2018) Tracks, we have extended the number of the scene categories from the initial 10 classes in the benchmark to 30 classes, resulting in two new and more challenging benchmarks SceneSBR2019 and SceneIBR2019. SceneSBR2019 has 750 2D scene sketches and 3,000 3D scene models. SceneIBR2019 has 30,000 scene images and 3,000 3D scene models. Your contributions will be very important since we plan to submit an extended journal version shortly after SHREC'19. Welcome to collaborate with us to publish a good journal together as well! If you have any questions, please feel free to contact the respective first organizer of each track as indicated above and on each track website as well. Please do send a registration email to the respective organizer ASAP, latest by February 8th, to indicate your interest in these two tracks. Please also help to forward this email to anyone who might be interested in these two SHREC'19 tracks. Thanks for your attention!
