20 Claims

1. A method comprising:

obtaining a raw image in a first image domain;

determining a color distribution and an amount of variation in the raw image; and

using an iterative process to generate a dead leaf image from a blank image in the first image domain, the iterative process comprising:

adding multiple circles and multiple sticks to the blank image until the dead leaf image is filled; and

blurring portions of the dead leaf image during at least one iteration of the iterative process;

wherein textures of the multiple circles are blended based on the color distribution and the amount of variation in the raw image.
