METHOD OF AUTOMATICALLY CREATING NATURAL IMAGE BY USING OPTIMIZATION TECHNIQUE

A method of automatically creating a natural image which may reduce the torment of creation which is a burden to a designer when creating a new image. To this end, the method includes an initial setting operation of setting an initial condition; a pre-process operation of setting a variable for a phase optimization process; a phase optimization operation of dividing an image to be created into finite elements, assigning values of material properties to the finite elements, performing filtering on the assigned values of the material properties, optimizing a design variable by using an optimization technique, updating a design variable obtained through the optimization process into a new design variable, determining whether the new design variable satisfies a preset convergence criterion, and if it is determined that the new design variable satisfies the preset convergence criterion, outputting a resultant structure; and a post-process operation of converting a final value of a design variable obtained through the phase optimization process into an RGB value of a digital image.
