1. 3D Shape Retrieval

1.1. Example-Based Shape Retrieval

1.2. Sketch-Based Shape Retrieval

Since a good example 3D shape is often not at hand, sketch-based retrieval has been proposed.

1.2.1. Category-level

• Sketch-based shape retrieval, ToG 2012, paper

1.2.2. Instance-level

2. Metrics

• Location Field Descriptors: Single Image 3D Model Retrieval in the Wild, 3DV2019
  • Top-k accuracy
  • HAU (mean modified Hausdorff Distance)
  • IoU (Intersection over Union)
