SAMPLE CODE

---

This page includes Matlab code and test programs for the algorithms described in the book. All the functions needed to run the sample programs and sample images can be obtained by downloading the examples-code.zip file.

• Algorithm 4.1 - Basic feature tracking/flow computation (sampleFlow.m)
• Algorithm 4.2 - Harris corner detector (harrisCorner.m, test_4_1.m)
• Algorithm 4.3 - Edge detection (edgeDetection.m)
• Algorithm 5.1 - The eight-point algorithm + 3D reconstruction (essentialDiscrete.m, , compute3Dstructure.m, test_5_1.m)
• Algorithm 5.2 - The four-point algorithm for planar scene (homography2Motion.m, test_5_2.m)
• Projetive reconstruction - fundamental matrix, projective reconstruction (dfundamental.m, compute3Dstructure.m, , test_6_1.m)
• Affine upgrade using vanishing points (from projective to affine) ( test_6_2.m)
• Algorithm 8.1 Factorization algorithm for multiview reconstruction using points (sfm_points.m )
• Algorithm 9.1 Factorization algorithm for multiview reconstruction using points and lines (sfm_mixed.m )
• Projective rectification (projRectify.m, Hwarp.m, test_11_9.m)
• Step-by-step reconstruction (quadric_linear_f.m , step_by_step.m)
