| Abstract: | A new definition of image information quantum is proposed. Five improved entropy information based on scientific segmentation methods for remote sensing images is brought forward. These algorithms are simulated with MATLAB,and some optimizations of algorithms' performances are made. The best thresholds and consumed time of different algorithms are compared and analyzed. These experiment data show that these new algorithms make qualitative improvements in precision and speed compared with other algorithms. |
