The method that will be called for descriptor matching with the following code `matcher = cv2.DescriptorMatcher_create(2)` is the Brute-Force matcher (BFMatcher).

Here's a step-by-step explanation:

1. `cv2.DescriptorMatcher_create(2)` is a function in OpenCV that creates a descriptor matcher object.

2. The argument `2` corresponds to the type of matcher to be created. In OpenCV, there are three types of matchers: Brute-Force matcher (BFMatcher), FlannBased matcher, and BruteForce-Hamming matcher. They are represented by the numbers 1, 2, and 3 respectively.

3. Therefore, `cv2.DescriptorMatcher_create(2)` creates a Brute-Force matcher.

4. The Brute-Force matcher is a simple descriptor matcher that matches the descriptors in the first set with the descriptors in the second set using a simple distance calculation.

5. After creating the matcher, you can use the `match()` or `knnMatch()` methods to match the descriptors.
