Hey, can you tell more about your output matrix ? if you want to do element wise comparision of the 3d matrix then you can simply run 3 for loops like this and apply the formula.
TP=0;FP=0;TN=0;FN=0;
for i=1:128
for j=1:128
for k = 1: 64
if(idxx(i,j,k)==1 && tempSeg1(i,j,k)==1)
TP=TP+1;
elseif(idxx(i,j,k)==0 && tempSeg1(i,j,k)==1)
FP=FP+1;
elseif(idxx(i,j,k)==0 && tempSeg1(i,j,k)==0)
TN=TN+1;
else
FN=FN+1;
end
end
end
end
Precision = TP/(TP + FP)
Recall = TP /(TP + FN)
