Coast line image data are compressed by first dividing the closed contour into segments at high curvature points. For each contour segment, we then compute complexity, which is similar to the fractal dimension, by a function we specially defined for this purpose. Each segment is coded by the coordinates of the two end points, the complexity and a shape pattern that roughly describes the way that the contour deviates from the straight line linking the two end points. In the recontruction stage, stochastical fractal is used to draw the coast line based on the complexity values and local shape patterns so that the resulting contour looks natural and at the same time is close to the original image.
