| Summary: | 碩士 === 國立臺灣大學 === 資訊工程學研究所 === 100 === Light painting is a photographic technique, where photographer takes a long exposure to record the light motion in the low light environment, like painting the world with light. However, the painting results are always unrecognizable because there are many differences between the exact motion paths we painted and ideal motion paths we wanted. In this thesis, we present a framework for synthesizing realistic long exposure images using example-based method to solve the problem above. In our approach , we synthesize the long exposure image guided by user strokes from input frames. With the spatial-temporal information of light source, we can edit the result of light painting such as its motion, color, line type, and scale while it still remains realistic interaction with environment. Moreover, we can combine the editing techniques mentioned above to synthesize a fabulous animation as its application.
