Non-photorealistic rendering (npr) is an area of computer graphics that focuses on enabling a wide variety of expressive styles for digital art, in contrast to traditional computer graphics, which focuses on photorealism. Npr is inspired by other artistic modes such as painting, drawing, technical illustration, and animated cartoons.

This thesis approaches the problem of non-photorealistic rendering by identifying seg-ments in the image plane and filling them using algorithms to render in artistic styles.

Non-photorealistic visualization and generalization are visual variables such as geometry, texture and distribution. Therefore, based on theories of modern cartography, computer graphics and data mining, this project proposes a non-photorealistic generalization method for 3d city models using visual variables mapping.

As images are increasingly used in wireless communication, such as mobile phones and pdas, it is important to reduce the energy consumption for transmitting and receiving images. The energy is approximately proportional to the sizes (numbers of bytes) of the images.
