方向相关的图像局部变形方法

Direction-correlating Image Local Morphing Method

针对传统的图像变形技术中所采用的径向基函数,应用在局部变形中的不足提出了一种改进方法:构造了基于多项式的分段连续基函数,并在此基础上引入了与方向相关的控制参数.该方法在图像局部变形的边界处具有光滑的过渡,同时克服了传统径向基函数的各项同性所导致的不合理变形现象.实验表明,该方法具有良好的局部变形效果.

Proposed an improved algorithm for traditional radial basis functions used in image morphing technology. Based on polynomial,the new basis function is continuous at subsections junctions,and introduced the direction-correlating control function. This algorithm keeps the boundaries of local morphed image subtle,and gets rid of some unreasonable warping resulted from isotropy with traditional radial basis functions. Experimental results show that good local morphing results can be achieved.
