	I explain how to make green noise. Step 1: Fill half of the image with random black and the other half with white dots. This random seed will be a key. Step 2: Next, perform a two-dimensional fourier transform of the dot pattern to obtained image P. Step 3:For¡¡frequency picture-transformed image P, filter D which has a constant value (=1) in the band confined to a certain region is filtered to obtain a new image P¡¯. Step 4: Perform an inverse Fourier transform on image P' to obtain a multi-level dot pattern 𝑝¡Ç.Step 5: Calculate the error function e, and invert the same number of white and black dots in descending order of the error values. Step 6: Repeat Step 2~5 to obtain the desired dot pattern.
