基于不同区域的亚像素的插值方法

在图像检测和定位过程中 ,需要高精度的图像特征 ,为了突出主要的特征 ,采用了分区域的亚像素插值方法。对于主要特征区域——边缘区域 ,根据其分形特性 ,用了高精度的分形插值方法。对于不感兴趣的区域——非边缘区域则用了线性插值方法 ,以节省运算时间。文中并给出了实验结果并验证了算法的有效性

Subpixel interpolation method based on different regions

High precision features are demanded in image detection and registration.So the subpixel interpolation method was adopted in order to emphasize the main features.The fractal interpolation is adopted in the main-feature-region,which is the edge-region in the image,according to its fractal property.And the linear interpolation method is adopted in the uninterested region,which is the non-edge region,in order to save the calculation time.The experiment results are given and the efficiency is confirmed.
