This code is provided to help gather statistics on your results on the
changedetection.net dataset.

Please use Python3 or the stats file won't work.

If you use MS Windows, the executable is already in exe\comparator.exe
Otherwise, you need to build the comparator. 
- cd to "c++ code/" and call  "make"
- copy comparator to ../exe/
- rename "comparator.exe" to "comparator" on line 56 of processFolder.py

Call "python processFolder.py datasetPath binaryRootPath"
ex :  "python processFolder C:\dataset C:\results"

	*** This code calculates 7 metrics, namely (1)Recall, (2)Specificity, (3)FPR, (4)FNR, (5)PBC, (6)Precision, (7)FMeasure. The metric "FPR-S" is only calcualated for "Shadow" category on the server side, but not in this code. If it's really necessary, 

FPR_S = float(nbShadowError) / nbShadow

where nbShadowError is the number in the last column in the 'cm' file you get, that is the number of times a pixel is labeled as shadow in GT but detected as moving object. nbShadow is the total number of pixel labeled as shadow in GT for a video or category.****
