一种运动模糊图像的模糊参数估计方法
在摄取图像的过程中,物体间的高速运动及景物与成像设备的相对运动是引发图像退化的主要原因之一,称之为运动模糊。模糊长度和模糊方向是运动模糊中影响图像模糊程度的主要参数。提出了一种改进的误差参数分析方法,对模糊长度进行估计并比较了不同的复原方法对参数误差曲线法估计的效果,同时提出运用傅里叶分解和Hough变换从模糊图像的频谱特性上对运动模糊方向进行了估计。实验结果表明,所提出的方法对运动模糊图像的复原有良好的效果。...

The blur length and the blur direction are main factors affecting the blur. A novel error parameter estimation method is proposed to identify the blur length and the impact of different restoration methods on the results are compared. Fourier decomposition and Hough transform are adopted to estimate the motion blur direction from the spectrum properties of a blurred image. Experiments validate the good effectiveness of our method. motion blur; blur length; blur direction; error parameter curve; spectrum properties;Hough transform |
