我们从图像灰度特征 ,直方图 ,频带 ,图像理解的变化等方面初步定义了图像感知信息参量 ,并利用sigmoid函数给出了感知信息的初步计算方法 ,实验结果初步说明了感知信息的有效性和可行性

• We define some perceptive parameters,such as the change of texture character,histogram,frequency spectrum,knowledge of image,and we calculate the perceptive information using sigmoid function. The results show that the perceptive information is valid and reasonable.
