Intensive search schemes are commonly adopted in patched-based texture synthesis to identity the proper neighbors of each patch. However, they do not always provide perfect solutions. This work presents a genetic algorithm in evolutionary computation for patch-based texture synthesis. The representation of an input source texture is first adjusted. Then, the synthesizing result is generated and refined by the selection of individuals based on their fitness and executing crossover and mutation until the criteria are met. After the entire execution, a large output texture is generated with texture features similar to the source texture. Because this approach optimizes the genetic algorithm, the results are satisfactory.

The tsunami which happened in 2004 has made lots of damages, and people saw the video from TV, they finally know how terrible the tsunami is. However, the movements of tsunami waves are not like those which are shown in Hollywood movies. In ocean engineering, they only simulate the surface of the tsunami wave movements, and the simulations are not rendered in a realistic way. In computer graphics, the ocean simulations often show the results which focus on the small movement on the ocean surface. In this thesis, we want to combine advantages in these two domains. We hope that we can simulate the tsunami wave propagation by physically-correct equations developed in ocean engineering and we render the simulated scene by the techniques developed in computer graphics to make it realistic. And we hope that our simulation system can make people having more understanding about tsunami waves.
