摘要: 基于P-M方程可以进行梯度和等照度线两个方向的分解,将其引入Criminisi算法,提出一种改进的基于样例的目标物体移除方法。该方法在平坦区和边界区有不同的优先权计算模式,可以获得更加可靠的优先权值,使修复后的图像不仅具有等照度线的连通性而且边缘得到强化。

Abstract: Based on P-M equation can be decomposed in two directions of gradient and isophote,the P-M equation is applied into Criminisi’s method to build an improved exemplar-based object removal method,which has different modes in calculation of priority in the smooth region and edge.The experimental results indicate that this method has the isophote connectivity and edge-enhancement for image inpainting.
