标题: 工业视觉halcon inpainting_ct函数介绍
inpainting_ct(Image, Region : InpaintedImage : Epsilon, Kappa, Sigma, Rho, ChannelCoefficients : )
inpainting_ct通过将图像信息从区域边界沿相干方向传输到该区域来绘制图像的缺失区域Region。

参数：
Image 输入的图像
Region 要修复的区域
InpaintedImage 已修改的输出图像
Epsilon 像素邻域的半径。
Kappa 锐度参数(百分数)。
Sigma 预平滑参数
Rho 方向估计的平滑参数。
ChannelCoefficients 通道权重。

2.inpainting_mcf(Image, Region : InpaintedImage : Sigma, Theta, Iterations : )
inpainting_mcf通过平滑图像Image灰度值函数的水平线，
将与输入图像Image的区域Region 相邻的图像边缘扩展到区域内部，
并将它们的端点连接起来。
参数：
Image 输入的图像
Region 要修复的区域
InpaintedImage 已修改的输出图像
Sigma 导数算子的平滑。

Theta 时间步长。
Iterations 迭代次数。
