The gestalt Principle of invariance basically means that even if an image is warped, turned, stretched, or distorted, we can still recognize that it is the same image. The first picture is the basic rundown of this idea, that through many different types of change we can still recognize that all of those shapes are the same shape. The bottom piece is a good example of this, that we can tell, even though the reflection is a turned version, as well as being distorted, that the reflection is the reflection of the woman.
