 - `exhaustive`: the images are divided into a regular grid of size 2400x2000 px to extract the features. The matching is carried out by matching all the possible combinations of tiles (brute-force). This method can be very slow for large images or in combination with the `highest` quality option and, in some cases, it may lead to error in the geometric verification if too many wrong matches are detected.
 
 To control the tile size and the tile overlap, refer to the [Advanced configuration](./advanced_configuration.md) section.
