### Two years later, I went back to Gestalt Theory

Two years later, reading the chapter The Helmholts Principle again, I am astonished by this statement again.

"We immediately perceive whatever could not happen by chance"

It gives us a simple, so simple, criteria to check whether a visual event is meaningful. If some event does not happen by chance, it is meaningful.

There exists a whole system developed to measure meaningfulness in this sense, aka $\delta$ meaningful.

It then relates to several bounding theories from Theoretical Computer Science smoothly.

I found F. Cao is doing very interesting work under this trend:
