1. 提取目标区域的初始边界
2. 重复以下步骤
?? 1）判断是否还存在待填充区域，如果不存在，则退出
?? 2）计算每一个边缘像素点块的优先级
?? 3）选出最大优先级点，基于该点查找最佳匹配块
?? 4）将最佳匹配块的值复制到对应的目标区域
?? 5）更新目标区域的边界与置信度值(1. Extracting the initial boundary of the target region

2. Repeat the following steps

1) Determine whether there is still an area to be filled, and if not, exit.

2) Calculate the priority of each edge pixel block

3) Select the maximum priority point and find the best matching block based on it

4) Copy the value of the best matching block to the corresponding target area

5) Update the boundary and confidence value of the target area)
