Crowd counting is the act of counting the total crowd present in a certain area. The people in a certain area are called a crowd. The most direct method is to actually count each person in the crowd.

Since the early 2000s, there has been a shift in the understanding of the phrase “crowd counting”. Having moved from a simpler crowd counting method to that of clusters and density maps, there are several improvements for crowd counting methods. Crowd counting can also be defined as estimating the number of people present in a single picture.

The only correct method is to count everyone upon entry. Everything else is an estimate.

according to the article that's the "modern understanding"

Still the sole correct method. An estimate isn't the same as counting.

A mathematician, a physicist, and an engineer were asked to review this mathematical problem. In a high school gym, all the girls in the class were lined up against one wall, and all the boys against the opposite wall. Then, every ten seconds, they walked toward each other until they were half the previous distance apart. The mathematician, physicist, and engineer were asked, “When will the girls and boys meet?”

The mathematician said, “Never.”

The physicist said, “In an infinite amount of time.”

The engineer said, “Well... in about two minutes, they'll be close enough for all practical purposes.”

Mathematician: Pi is the number expressing the relationship between the circumference of a circle and its diameter.

Physicist: Pi is 3.1415927 plus or minus 0.000000005.

Engineer: Pi is about 3. But we'll round it up to 5 to be safe.
