Sketch-Based Articulated 3D Shape Retrieval.
IEEE Computer Graphics and Applications 2017 November
Sketch-based queries are a suitable and superior alternative to traditional text- and example-based queries for 3D shape retrieval. The authors developed an articulated 3D shape retrieval method that uses easy-to-obtain 2D sketches. In contrast to existing sketch-based retrieval systems that lower the 3D database models to 2D, their algorithm implicitly lifts the 2D query to 2.5D by inferring depth information from possibly self-intersecting sketches using a good continuation rule. It does not require 3D example models to initiate queries, but results show that it achieves accuracy comparable to a state-of-the-art example-based 3D shape retrieval method.
