Description: We compiled three large sets of images for the 'How low can you go' project, spanning three domains: paintings, birds, and faces. Each set consists of two subcategories: 2,592 paintings (half Cubist and half Impressionist), 1,502 birds (half hawks or Accipitridae and half owls or Strigidae), and 1,772 faces (half females and half males). We generated eight different versions of every image in our three sets, at 1 pixel, 2×2, 4×4, 8×8, 16×16, 32×32, 64×64, and 128×128 pixels, using a nearest neighbor resampling procedure in Matlab. All images were then upsampled to 256×256 pixels.
