  The SHApe Recovery from Partial textured 3D scans challenge, SHARP 2020, is
the first edition of a challenge fostering and benchmarking methods for
recovering complete textured 3D scans from raw incomplete data. SHARP 2020 is
organised as a workshop in conjunction with ECCV 2020. There are two
complementary challenges, the first one on 3D human scans, and the second one
on generic objects. Challenge 1 is further split into two tracks, focusing,
first, on large body and clothing regions, and, second, on fine body details. A
novel evaluation metric is proposed to quantify jointly the shape
reconstruction, the texture reconstruction and the amount of completed data.
Additionally, two unique datasets of 3D scans are proposed, to provide raw
ground-truth data for the benchmarks. The datasets are released to the
scientific community. Moreover, an accompanying custom library of software
routines is also released to the scientific community. It allows for processing
3D scans, generating partial data and performing the evaluation. Results of the
competition, analysed in comparison to baselines, show the validity of the
proposed evaluation metrics, and highlight the challenging aspects of the task
and of the datasets. Details on the SHARP 2020 challenge can be found at
