Patch-wise continuous approach to image zooming.
Guozhao Wang · Journal of Zhejiang University(Sciences Edition) · 2002
Image zooming is an important operation for image processing and visualization, but one main shortcoming of some existing zooming methods is that the object borders may be blurred after transformation. A new image zooming method based on patch-wise continuous surface fitting is presented. With this approach a large varieties of gray images can be zoomed efficiently and keep the clear borders of source images clearly.
