本文针对自动X线头影测量系统中X线片的处理问题,提出了一种空间非均匀图像噪声去除的卡尔曼滤波方法.该方法将图像的边缘信息加入了滤波器输入,在进行滤波的同时可以有效地保持图像的边缘,并且可以避免由于图像模型参数的辨识而引起的计算上的负担.
In order to solve the problem of X-ray film processing in the automatic X-cephalometry system, this paper proposes a Kalman filter method for removing non-uniform spatial image noise. This method adds the edge information of the image to the filter input, The edge of the image can be effectively maintained and the computational burden due to the identification of the image model parameters can be avoided.
