Batch quantify black levels / output histogram data

[ArchAnGeL]

Ok, bit of a strange request this one but here goes.

I have a series of B&W images (several thousand) and need to quantify the amount of black in each one

They are basically CT scans so I am thinking I need the histogram areas split into 0 to 255 or say the total area between say 0 and 155.

This needs to be per image and output into a common file e.g csv, xls etc so I can quantify it.

I know this is possible manually so hopefully someone has an idea on how to automate/batch process this

Thanks

If it help or jogs any memories, I can see how this would be possible in imageJ but I don't understand the macro language

Thanks for the pointers. Probably more confused by gimp than imagej at this stage

So is that running just in python or using python to script another prog?
