The demo contained in this package is described in Balanced Exploration and Exploitation Model Search for Efficient Epipolar Geometry Estimation Liran Goshen, Ilan Shimshoni in the proceedings of ECCV 2006. Please refer to the paper for details The main function in this package is: [InIndex, F]=BEEM(p1_m, p2_m, rr1, rr2, distanceRatio, N_BEEM) Output: InIndex- Index of inliers F- Fundamental matrix Input: p1_m, p2_m- putative match (Enclose are example files). rr1, rr2- SIFT parameters for the putative match. rr1 for p1_m and rr2 for p2_m. The first column in rr1/rr2 is the rotation angle of the dominant gradient of the SIFT descriptor. The second column is the scale in the space scale of the SIFT descriptor (Enclosed are example files). distanceRatio - the distance ratio of the closest to the second-closest neighbors of the keypoint of the first image ($r_i$ in the paper). (Enclose is example file). N_BEEM- Maximum number of iteration (default value is 500). Note: The program was written under MATLAB v6.1.
