1. A computer-implemented method comprising:
receiving an input image;
computing an outline of the input image;
identifying a set of candidate color handles for the input image, each candidate color handle of the set of candidate color handles representing an extremum point for a color in the input image;
generating a reconstructed image using a subset of the set of candidate color handles;
determining a reconstruction error by computing a difference between the input image and the reconstructed image; and
providing the reconstructed image when the reconstruction error is below a threshold value.
