another thing is do you know what are these mean at your preset.txt?
especially, like this {{a,b,c},{d,e,f}} What does mean a,b,c,d,e,f ?

[darktable-devel] I have found a bug in noiseprofile.c.
Dear all,
I have found a bug in noiseprofile.c.
The bug code as following.
std[bin][c] += median(llhh+2*begin, end-begin)/0.6745;
As you can see, above std[bin][c] does not accumulated.
I used printf function to probe as following code.
printf("acc_std:%f std:%f cnt:%f bin:%d c:%d \n",std[bin][c],(kk)
,cnt[bin][c],bin,c );
and result as following.
acc_std:0.51 std:0.51 cnt:1058.00 bin:0 c:0
acc_std:0.000113 std:0.000113 cnt:4416.00 bin:1 c:0
acc_std:0.000226 std:0.000226 cnt:3520.00 bin:2 c:0
acc_std:0.000294 std:0.000294 cnt:3057.00 bin:3 c:0
acc_std:0.000339 std:0.000339 cnt:3197.00 bin:4 c:0
acc_std:0.000633 std:0.000633 cnt:2325.00 bin:5 c:0
acc_std:0.000814 std:0.000814 cnt:2230.00 bin:6 c:0
acc_std:0.000905 std:0.000905 cnt:2736.00 bin:7 c:0
...
As you can see that above, acc_std does not increase.
it seems to be a bug. If not , Please let me know.
Does anyone let me know whether this is a bug or not?.
cheers

Following code is that i used code in noiseprofile.c.
...
kk = median(llhh+2*begin, end-begin)/0.6745;
std[bin][c] += median(llhh+2*begin, end-begin)/0.6745;
cnt[bin][c] = end - begin;
printf("acc_std:%f std:%f cnt:%f bin:%d c:%d \n",std[bin][c],(kk)
