Members

FLANNBASED

• FLANNBASED = 1

FLANN-based matcher (Fast Library for Approximate Nearest Neighbors). Good for large descriptor sets where approximate search is acceptable.

---

BRUTEFORCE

• BRUTEFORCE = 2

Brute-force matcher: compares every descriptor pair. Accurate but slower on large inputs.

---

BRUTEFORCE_L1

• BRUTEFORCE_L1 = 3

Brute-force matcher using L1 (Manhattan) distance.

---

BRUTEFORCE_HAMMING

• BRUTEFORCE_HAMMING = 4

Brute-force matcher using Hamming distance. Suited to binary descriptors (e.g. ORB).

---

BRUTEFORCE_HAMMINGLUT

• BRUTEFORCE_HAMMINGLUT = 5

Brute-force matcher with a Hamming LUT for faster binary-descriptor matching than plain BRUTEFORCE_HAMMING.

---

BRUTEFORCE_SL2

• BRUTEFORCE_SL2 = 6

Brute-force matcher using L2 (Euclidean) distance.
