| 摘 要： | 对基于微分方程(partial differential equation,PDE)的图像放大方法的实现及应用效果进行了比对研究.具体实现了朱宁等人的线性PDE图像放大方法和基于P-M方程的非线性PDE图像放大方法.实验结果表明,线性PDE图像放大方法在平滑区域具有较好的放大效果;而在放大倍数不大的情况下,非线性PDE图像放大方法能更好地处理边缘区域.

| Abstract: | The implementation and application results of linear and nonlinear image zooming methods based on PDE (partial differential equation) are compared and studied.It is shown that the linear PDE method has better zooming processing result in smooth region,while the nonlinear PDE method has better zooming processing in edge region.The nonlinear PDE method is better than the linear PDE method under less zooming amplification. |
