Computer-aided-pattern design systems are now widely used by designers to reduce the time and expences in generating new patterns. However, currently-available commercial systems are either restricted to generate geometric patterns, or not yet enough to offer an automatic and efficient tools for making natural patterns.
In this thesis, we develop an interactive pattern design system, which generates aesthetic patterns from scanned images. Pattern is generated in our system by the following four steps: motif extraction, motif simplification, motif drawing, motif placement.
In developing our system, we have tried to make the system satisfy both of the two conflicting demands: minimizing manual tasks and maximizing interactivity. We enhance interactive techniques for motif extraction and simplification. We also propose various drawing tools to add artistic effects on a simplified motif.
Using our system, designers can easily generate a nice pattern from an initial image by interactively following the given steps. Experimental results show how each technique is used and what effect it has.
