--seuil-coche threshold does not exist?

Added by Nhu Le about 11 years ago

I am trying to use a lower value for this option. However, when I run the command 

auto-multiple-choice analyse --no-multiple --seuil-coche 0.09 --tol-marque 0.2,0.2 --prop 0.8 --bw-threshold 0.6 --progression-id analyse --progression 1 --n-procs 0 --data /home/nle/MC-Projects/dhcd2/data --projet /home/nle/MC-Projects/dhcd2/ --cr /home/nle/MC-Projects/dhcd2/cr --liste-fichiers files_to_scan.txt --no-ignore-red

The output: 
Unknown option: seuil-coche
OpenCV Error: Bad argument (Bad image header) in cvCloneImage, file /builddir/build/BUILD/OpenCV-2.3.1/modules/core/src/array.cpp, line 3108
terminate called after throwing an instance of 'cv::Exception'
  what():  /builddir/build/BUILD/OpenCV-2.3.1/modules/core/src/array.cpp:3108: error: (-5) Bad image header in function cvCloneImage

In the GUI, I specified the threshold to be 0.09 as well but I don't see that reflected anywhere in the command. Does it get passed to the command as executable parameters or by some other mean?

--seuil-coche is an old option that has been dropped. AMC-analyse now only measures the darkness ratio of each box on the scan. It is not AMC-analyse that is responsible to say if a box is considered as being ticked or not, but AMC-note.
The OpenCV error tells you that OpenCV couldn't read your scan file. Is this a standard raster image? OpenCV can't read PDF files, for example.

If I remove the seuil-coche then there would be no error and everything works. I guess opencv probably thinks the option is the file to be process or something???

That option is still in the documentation so may be we should remove that reference.

That can be the problem. Requesting a debugging log would confirm that.

Yes! I updated the documentation in revision r1358.
