Boundary_weightmap

[HUI623]

Thank you for your sharing. I have some quesions ：

1.  “   boundary_weightmap_lesion = 0.75*np.clip(np.exp(-0.02*(ndi.morphology.distance_transform_edt(1-total_border))),weight,None)+0.25*lesion_mask
   

   boundary_weightmap_liver = 0.65boundary_weightmap_liver + 0.35boundary_weightmap_lesion”
   Q：
   (1) Did boundary_weightmap formula come from ‘ weight_map = wc+w0 * np.exp(-1/2 * ((d1+d2)/sigma) ** 2) ’？
   (2) How to determine the coefficients of the weight formula to be 0.75 and 0.25，0.65 and 0.35？
   (3) How is this boundary_weightmap sent to the network? to which part of the network？

2." if opt.Training['data']=='lesion': vol_info['ref_mask_info']= pd.read_csv(opt.Paths['Training_Path']+'/Assign_2D_LiverMasks.csv', header=0)"
Q：What does this code mean？Why 'data' is'lesion', but Assign_2D_LiverMasks.csv is given to ref_mask_info？

Looking forward to your answer, thank you very much！
