Knowledge-based natural scene description

The authors present a knowledge-based image description system that uses fractal features. A knowledge-based recognition process is incorporated in this natural scene description system to enhance the capability of natural scene understanding. The scene description system is based on a fractal model. The fractal model provides useful information. A set of fractal features was developed from the fractal model which can effectively be used in image segmentation. After an image is divided into many regions based on fractal features, the scene information is derived with a knowledge-based scene recognition process. The structure of this system and its interaction strategy for the extraction of scene description are presented. The experimental results are also discussed
