GRSL-2020-1 The README shows how to use the codes made to perform the numerical tests of the article submitted for: GRSL - IEEE Geoscience and Remote Sensing Letters Fusion of Evidences in Intensities Channels for Edge Detection in PolSAR Images Anderson A. de Borba, Maurı́cio Marengoni, and Alejandro C Frery

Test to Flevoland image In Matlab/Octave

1. Run /Code_matlab/imagem_real_lin_radial_flev.m
   • Read data base /Data/AirSAR_Flevoland_Enxuto.mat
   • Write ray in: (There are 9 channels, but we use 3 to intensities) /Data/ a) channel hh - flevoland_1.txt b) channel hv - flevoland_2.txt c) channel vv - flevoland_3.txt
   • Write ray coordinate in: /Data a) File xc_flevoland.txt b) File yc_flevoland.txt

In R 2) Run /Code_r/evidencias_im_real_sa_param_mu_L.R
- Read data base /Date
a) Channel hh - flevoland_1.txt b) Channel hv - flevoland_2.txt c) Channel vv - flevoland_3.txt - Write edge evidences
/Data a) Channel hh - evidence_flev_hh.txt b) Channel hv - evidence_flev_hv.txt c) Channel vv - evidence_flev_vv.txt

In Matlab/Octave 3) Run /Code_matlab/det_bordas_fusion_put_point_flev_r3.m - Read data base /Data/AirSAR_Flevoland_Enxuto.mat - Read edge evidences
/Data a) Channel hh - evidence_flev_hh.txt b) Channel hv - evidence_flev_hv.txt c) Channel vv - evidence_flev_vv.txt - Read ray coordinate in: /Data a) File xc_flevoland.txt b) File yc_flevoland.txt
- Show the fusion Images

4. Run /Code_matlab/gt_flevoland_r3.m

   • Read data base /Data/AirSAR_Flevoland_Enxuto.mat
   • Write ground truth /Data/gt_flevoland.txt

5. Run /Code_matlab/metricas_gt_flevoland.m

   • Read edge evidences
     /Data a) Channel hh - evidence_flev_hh.txt b) Channel hv - evidence_flev_hv.txt c) Channel vv - evidence_flev_vv.txt
   • Read ray coordinate in: /Data a) File xc_flevoland.txt b) File yc_flevoland.txt
   • Read ground truth /Data/gt_flevoland.txt
   • Write probabilities error in /Data/metricas_fusao_flevoland.txt

In R 6) Run /Code_r/metricas_fusao_flev.r - Show probabilities error

   • Write ray coordinate in: /Data a) File xc_san_fran.txt b) File yc_san_fran.txt

In R 2) Run /Code_r/evidencias_im_real_sa_param_mu_L_san_fran.R
- Read data base /Date
a) Channel hh - san_fran_1.txt b) Channel hv - san_fran_2.txt c) Channel vv - san_fran_3.txt - Write edge evidences
/Data a) Channel hh - evidence_san_fran_hh.txt b) Channel hv - evidence_san_fran_hv.txt c) Channel vv - evidence_san_fran_vv.txt

In Matlab/Octave 3) Run /Code_matlab/det_bordas_fusion_put_point_san_fran_r1.m - Read data base /Data/SanFrancisco_Bay.mat - Read edge evidences
/Data a) Channel hh - evidence_san_fran_hh.txt b) Channel hv - evidence_san_fran_hv.txt c) Channel vv - evidence_san_fran_vv.txt - Write ray coordinate in: /Data a) File xc_san_fran.txt b) File yc_san_fran.txt - Show the fusion Images

4. Run /Code_matlab/gt_san_fran_r1.m
