Different ways of segmentation for cloud images have been developed. The time complexity of these algorithms become vital for implementation. Implementation of Otsu's method of thresholding for segmentation purpose take reasonable computational time for multiple class problem. In this paper, a fractal based segmentation method is developed. The technique is compared to modified version of Otsu's algorithm with reduced time complexity. The time complexity of the fractal based method is favourable and the results of segmentation are also comparable.
