The module is intended for aligning and cropping an object in the image. You can use it if the object is in a different position (rotated, shifted) in each image. After its application, all images are in the same position and at the same angle.
The module works with templates that are created from sample images.
To use the module, it is necessary to have at least two objects detected and classified (e.g. using a detector with classifier).
This specifies which objects are used for alignment. If more than 2 objects are detected in an image, some of them may be ignored. The more active objects, the better the accuracy.
