| 摘 要： | 数字图像的增强以及边缘检测是数字图像处理中的重要内容。根据B-样条函数插值公式,对图像灰度点像素值进行三次B-样条插值运算,提出了基于三次B-样条插值的分数阶增强模板以及分数阶CRONE边缘检测模板。通过对比实验表明,所设计的模板能根据对图像的需求而改变阶次,在图像增强方面能较好地提升图像边缘并且加强纹理细节,在边缘检测方面有良好的边缘定位能力,优于基于Sobel算子的传统方法。

| Abstract: | The digital image enhancement and edge detection is an important part in digital image processing. According to the B-spline function interpolation formula, the cubic B-spline interpolation is used to calculate the gray of pixels of the image, then the fractional order enhancement template and the fractional order CRONE detection template based on the cubic B-spline interpolation are proposed. The experiments show that the designed templates could implement order change on the needs of the image. In image e... |
