Code自适应
传统的图像分割方法可以分为基于阈值、边缘、区域的方法等,而传统的分割方法在复杂图像分割中效果不好。为了提高图像分割的性能,我们提出了一种基于局部自适应窗口的Otsu方法。首先,分析了传统阈值法在复杂图像分割中不能很好地形成的原因,比较了全局阈值和局部阈值对图像分割的影响。其次,提出了根据局部信息自适应地改变局部窗口大小的方法,分析了该方法的特点。最后,证明了所提出的新方法优于其他方法。实验结果表明,与其他传统方法相比,该方法能保持更多的细节,获得更满意的结果。(The traditional image segmentation methods can be divided into thresholding, edge and region methods. The traditional segmentation methods do not perform well in the segmentation of complicated images. In order to improve the performance of image segmentation, we propose an adaptive windowed range-constrained Otsu method based on local information.First, the reason why traditional thresholding methods do not perform well in the segmentation of complicated images is analyzed. Therein, the influences of global and local thresholdings on the image segmentation are compared. Secondly, a method of adaptively changing the local window size based on local information is proposed, and the characteristics of the proposed method are analyzed. Finally, the superiority of the proposed method over other methods, It is validated by the experiments that the proposed method can keep more details and acquire much more satisfying results as compared with the other conventional methods.)

曲面拟合法是一种高精度、计算量小、抗噪性能强的方法,当前已被广泛地应用于
各种场景。比如岩石材料的变形测量、电子器件变形的测量、基于掌纹图像相关匹
配的重复定位技术等。曲面拟合法能够成功计算出亚像素位移的前提是整像素搜索阶
段可以正确搜索出模板的整像素匹配点,一旦整像素匹配点搜索出现错误,那么亚像素
测量阶段所得到的位移距离就会失去意义。
使用不同的拟合函数对相关系数矩阵进行曲面拟合,会对结果产生一定的影响,比
较常用的拟合函数有二次函数、三次函数、高斯函数等。(Surface fitting method is a high-precision, computational complexity is small, strong anti-noise performance method, has been widely used in various scenes. For example, deformation measurement of rock materials, deformation measurement of electronic devices, and repetitive location technology based on palmprint image correlation matching. Surface fitting method can successfully calculate the sub-pixel displacement on the premise that the whole pixel search stage can correctly search the template of the whole pixel matching point, once the whole pixel matching point search error, then the sub-pixel measurement phase of the displacement distance will be meaningless.
Using different fitting functions to fit the surface of the correlation coefficient matrix will have a certain impact on the results. The commonly used fitting functions are quadratic function, cubic function, Gaussian function and so on.)
