Sketch-based 3D Shape Retrieval using Convolutional Neural Networks (pdf)

Fang Wang, Le Kang, and Yi Li

We visualize the retrieval results for SHREC13 dataset in this demo. The window on the left shows the Sketch-Map, which is the 2D PCA projection of the learned CNN feature. Each hexagon represents a number of data points within the region, and one sketch is shown in the center. Different color denotes different data point density in the region. Please use the scroll wheel to zoom in and discover more sketches.

As mentioned in the paper, we include the precision-recall curves for the PSB/SBSR here and here. The core of the python code for our model can be viewed here.
