A comparison of methods for sketch-based 3D shape retrieval

Artículo de publicación ISISketch-based 3D shape retrieval has become an important research topic in content-based 3D object retrieval. To foster this research area, two Shape Retrieval Contest (SHREC) tracks on this topic have been organized by us in 2012 and 2013 based on a small-scale and large-scale benchmarks, respectively. Six and five (nine in total) distinct sketch-based 3D shape retrieval methods have competed each other in these two contests, respectively. To measure and compare the performance of the top participating and other existing promising sketch-based 3D shape retrieval methods and solicit the state-of-the-art approaches, we perform a more comprehensive comparison of fifteen best (four top participating algorithms and eleven additional state-of-the-art methods) retrieval methods by completing the evaluation of each method on both benchmarks. The benchmarks, results, and evaluation tools for the two tracks are publicly available on our websitesArmy Research Office grant W911NF-12-1-0057, Texas State University Research Enhancement Program (REP), NSF CRI 1305302, Fondecyt (Chile) Project 1110111, Pest-OE/EEI/LA0021/2013, Fraunhofer IDM@NTU, National Research Foundation (NRF), Interactive & Digital Media Programme Office (IDMPO), Media Development Authority of Singapore (MDA)
