The difference between mirror flip and horizontal flip

Mirror flipping and horizontal flipping are both operations of flipping images, but their results are different from those in application scenarios.

Mirror image flip is to flip the image horizontally and vertically, that is, to flip the image 180 degrees with the image center as the axis. As a result of this operation, the image on the left is now on the right, and the image above is now below. This operation is very common in some image processing software.

Horizontal flip is to flip the image left and right and swap the left and right sides of the image. As a result of this operation, the left image is now on the right, and the right image is now on the left. This operation is common in some post-processing of photography.

In practical application, mirror image flip is often used to correct some shooting angle problems, such as head down or up when shooting people; Horizontal flip is often used to deal with symmetrical images, for example, when shooting a building, it is necessary to reflect its symmetrical aesthetic feeling.
