| 摘 要： | 提出了一种新的图像模糊测度方法,该方法以图像小波分解的低频系数各个方向上的信息梯度和作为图像的模糊测度,理论与实验证明该测度相对于图像的模糊程度是单调和单峰的,并且受噪声、亮度和对比度变化影响较小。

| Abstract: | A new measure of image blurting based on orientation information gradient is proposed,The measure is defined as a summation of orientation information gradient of the image wavelet decomposition approximation coefficients,It is shown that the blur measure is monotonic and unimodal with respect to image blurring.Additionally,it is invariant to contrast or brightness changes due to the differences in the intensities of illumination.The measure is also shown to be robust to noise. |
