In this paper, we categorize shadows as either powerful or poor on the basis of the ratio between background light intensity and direct light-intensity, and make use of the fractal web evolution approach (FNEA), that is a multi-scale segmentation method based on spectral and form heterogeneity, to cut back the disturbance of salt and pepper sound and relieve the error of misdiagnosing land covers with a high reflectivity in shaded regions as unshaded people. Consequently, an object-b
