image_diffuse, an Octave code which uses diffusion to smooth out an image.

Source Code:

• image_diffuse_test.m, calls all the tests.
• image_diffuse_test.sh, runs all the tests.
• image_diffuse_test.txt, the output file.

FOOL is an image which was originally a true black and white image; that is, as a gray scale image, every pixel was set to 0 or 255. Diffusion will smooth the boundary between the black and white areas.

• fool.png, the original image.

Diffusion using image_diffuse4():

• fool_c0.05_k20_n4.png, the result for C = 0.05, K = 20;
• fool_c0.50_k01_n4.png, the result for C = 0.50, K = 1.
• fool_c0.50_k20_n4.png, the result for C = 0.50, K = 20.
• fool_c1.00_k01_n4.png, the result for C = 1.00, K = 1

Diffusion using image_diffuse8():

• fool_c0.05_k20_n8.png, the result for C = 0.05, K = 20;
• fool_c0.50_k01_n8.png, the result for C = 0.50, K = 1.
• fool_c0.50_k20_n8.png, the result for C = 0.50, K = 20.
