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)
