The WorldView-1 satellite can provide panchromatic image with a dramatic improvement in spatial resolution, among these the feature extraction of vegetation image has an important application in identification and classification. Taking the advantage of fractal theory in image identification and combining the character of WorldView-1 panchromatic vegetation image, the fractal dimension of WorldView-1 panchromatic vegetation image is caculated by applying the Hausdorff algorithm, Box counting algorithm, Euclidean distance map algorithm and Blanket algorithm. The result indicates the Blantket algorithm was the most stable when compared with the other three algorithm and is suitable for computing the fractal dimension of the WorldView-1 panchromatic vegetation image.
