图像熵在图像分割、图像识别领域应用广泛，如果考虑各像素之间统计独立，图像的一维熵可以表示图像灰度分布的聚集特征。(Image entropy is widely used in image segmentation and image recognition. If the statistical independence between pixels is considered, the one-dimensional entropy of the image can represent the aggregation feature of the gray distribution of the image.)
