On the contrary, as the car runs fast, we couldn't get stable background image, and we can get only one picture as it pass by the tollbooth in order to satisfy the request of real time processing. We proposed the method of differencing image in one frame to get the moving edge.

将一帧图像的两场作为不同时刻的图像，作前后帧减影，得到运动边缘，为了克服图像中的水平边缘分割为运动边缘的问题，我们提出了一种局部门限的方案，取得了很好的运动边缘分割效果。

On the bases of the inter-frame difference, we used the motion information of sequence images to extract binary image edges. Then according to the feature of head-shoulder image contour and chromatic coordinates transformation of color images motional face can be located.

该方法利用序列图像的运动信息，在帧间差分的基础上进行二值图像边缘提取，利用人的头肩轮廓特点以及彩色图像的色系坐标变换进行运动的人脸定位。

The feature points from two images were extracted by Harris corner detector, then the corresponding feature point pairs were got by the cross-correlation of the gray scale around the feature points, and the mismatched pairs were eliminated based on the Eulerian distance of the transformation parameter vector.

提出了一种基于特征点的图像拼接算法，首先利用Harris角点检测提取两幅图像中的特征点，用特征点邻域灰度相关性将特征点进行匹配，并在此基础上根据变换参数向量的欧式距离对误匹配进行剔除，进而实现图像拼接。

The experiment results on remote sensing image segmentation show that the improved method effectively increases the speed of image segmentation based on the texture,and keeps the accurateness of the fractal dimension with the triangular prism method.

The frequency range and distortion model affected by Faraday rotation were analyzed. A kind of calibration algorithm was introduced, in which trihedral corner reflectors were used to calibrate POLSAR image subject to channel imbalance, Faraday rotation and RCS distortion. [2]Three kinds of target decomposition theorems used to extract polarimetric features of SAR image were studied in detail. A kind of POLSAR MLC image data decomposition method based on classical coherent decomposition theorem of POLSAR SLC image was introduced, which was used to extract polarimetric features of POLSAR MLC image.

当工作频率小于1GHz时，法拉第旋转是影响低频星载极化SAR图像定标的一个重要因素，论文分析了受法拉第旋转影响的波段范围和误差模型，提出了一种校正通道不平衡度、法拉第旋转和绝对幅度增益的极化定标算法，仅使用一种点目标——三角反射器作为定标体，应用于受法拉第旋转影响的极化SAR图像定标； [2]深入研究了三类用于SAR图像极化特征提取的目标分解理论。

The aim of image restoration is to recover the original uncorrupted images from noisy, blurred ones.

图像复原的目的是将原始图像从观测到的降析图像中恢复出来。

After it is proved that the fractal dimensions are stable characteristic parameters of images, and there is correlation between them in undeformed and deformed states, the fractal correlation function are found for displacement measurement, which the correlation parameters are Box Dimensions.

在确定了变形前后数字散斑图像的分形维数之间具有相关性，而且其分形维数是稳定的特征参数之后，以图像的盒维数为相关参数进行互相关运算而形成分形相关函数。即利用变形前后数字散斑图像的分形维数序列做为相关参数进行相关运算，实现位移测量。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
