Detailed Description

Geometric Transforms engines are usually used to align images.

For example, if the subject and camera were not ideally positioned, rotating the image may improve visualization. Rotation and translation may be used to align successive sections of CT scans or confocal microscope images. A combination of geometric transformations sometimes is used to restore satellite or remote sensing images.

In addition, some Visilog operations, such as erosion, dilation, and even edge detection, are usually implemented for the main directions of the grid: $0^\circ$, $45^\circ$, $90^\circ$, etc. To erode an image in the $20^\circ$ direction, you could first rotate the image $20^\circ$, and then perform a $0^\circ$ erosion. Be careful since the rotation will distort the image due to resampling.
