To align 'this_img' with another image passed in through its parameters.
The alignment uses a user-given comparison method to compare the two images. If none is given, a default one is used.
this_img | The image to be compared. | |
to_img | 'this_img" is aligned with 'to_img'. | |
cmp_name | The comparison method to compare the two images. | |
cmp_params | The parameter dictionary for comparison method. |
