Filtering according to the size of the animal improves detection by eliminating certain areas detected incorrectly.
By default, the filtering uses the characteristics of the animal as defined in the "Animal" dialog box .
The min and max surfaces are calculated according to the following correspondence table:

You can also, for each test, choose not to filter by the size of the animal, or to use custom parameters. If you want to use custom settings, you must specify a minimum size and a maximum size for the animal:

When the animal is detected on an edge of the arena, a coefficient of 0.5 is applied to the minimum size to take into account the fact that the animal can climb on the walls of the arena.
The parameters are immediately applied to the video image, and each part of the image corresponding to the detection criteria is clearly identified:
