data

Joint Manifolds datasets: provides data from multi-camera acquisition of low-dimensional object articulations.

• Translating Coffee Mug (641M)
  

• Koala Bears (185M)
  

Both archived folders contain small Matlab scripts that read in the images, downsample them, and store the image data in a mat-file.
