A Gordon Walters' koru style filter
This program is inspired by The Koru series of Gordon Walters. It can create a random koru style image or can be used as an image/video filter.
The koru image is generated base on a low resolution image in grayscale. White pixels are used for representing circles. Also, the white pixels are checked and deleted to keep a suitable distance. So that the circles will not overlap eachother.
The basic generator method can create two random lines in grayscale image to simulate the painting on the poster.
