The general command line usage is shown below.

$ colortrans [--method METHOD] [--single-precision] CONTENT REFERENCE OUTPUT

CONTENT is the path to the content image, REFERENCE is the path to the style image, and OUTPUT is the path to save the output image.

METHOD specifies the color transfer algorithm. The following methods are supported:

  1. lhm Linear Histogram Matching [1] (default)
  2. pccm Principal Components Color Matching [2, 3]
  3. reinhard Reinhard et al. [4]

If the optional --single-precision flag is present, 32-bit floats will be used instead of 64-bit floats.
