# mondrian_map_generator

This is useful for generating test images for shadow removal algorithms

	%GEN_MONDRIAN Generate a mondrian image, illuminated with two spectra

	%   Parameter list:

	%       size_y - the number of rows that the resulting matrix has

	%       size_x - the number of columns that the resulting matrix has

	%       region_count - the number of rectangle to draw (they might overlap)

	%       bright_spectra - the spectra for the lit region

	%       shadow_spectra - the spectra for the shadowed region

	%       reflectance - the material's reflectance distribution

	%       device_respone - the response curve of the imaging device

	%

	%   Variable dimensions:

	%       bright_spectra and shadow spectra:

	%           n-vector, where

	%           - n is readings at individual bands,

	%       device_respones:

	%           n x 3 matrices, where

	%           - n is readings at individual bands

	%       reflectance:

	%           n x o matrices, where

	%           - n is readings at individual bands

	%           - o is the number of materials.

You will need to import the spectral data, camera response curve, and reflectance

from:

  - http://www.cs.sfu.ca/~colour/data/colour_constancy_synthetic_test_data/index.html
