图像的水平矫正

图像的水平矫正：
阈值分割---转化凸多边形----计算倾角----仿射变换

1. read_image (ImageOrig, 'blister/blister_reference')
   
2. access_channel (ImageOrig, Image1, 1)
   
3. threshold (Image1, Region, 90, 255)
   
4. shape_trans (Region, Blister, 'convex')
   
5. orientation_region (Blister, Phi)
   
6. area_center (Blister, Area1, Row, Column)
   
7. vector_angle_to_rigid (Row, Column, Phi, Row, Column, 0, HomMat2D)
   
8. affine_trans_image (ImageOrig, Image2, HomMat2D, 'constant', 'false')

shape_trans (Region, Blister, 'convex')
将断开的Region采用凸多边形的方式闭合处理。
