Image Mosaic Method Based on SIFT Features of Line Segment

Procedure 2

Method 2: computation procedure of matrix 𝐺.

(1) Initialize 𝐺∈𝑅^𝑛×𝑚 into null matrix

(2) For 𝑖=1,2,…,𝑛₁, 𝑗=1,2,…,𝑛₂

  (i) If 𝐾𝑖,𝑗=1

  (ii) According to the directed line segment 𝑙_𝑖 is 𝑎_𝑙→𝑎_𝑚, the directed line segment 𝑙^′_𝑗 is 𝑏_𝑝→𝑏_𝑞

  (iii) 𝐺𝑙,𝑝=𝐺𝑙,𝑝+1, 𝐺𝑚,𝑞=𝐺𝑚,𝑞+1

(3) Output matrix 𝐺
