Benchmark :

Some number to compare Camelot (a popular library to extract tables from PDF) and Colibrie

		Tables extracted
Times in second		camelot		colibrie
camelot	colibrie	valid	false positive	valid	false positive	pages count	pdf file
0.53	0.00545	1	0	1	0	1	small pdf
5.95	0.02100	4	0	4	0	11	medium pdf
105.00	0.21900	62	1	61	0	167	big pdf
182.00	0.69000	175	1	177	0	269	giant pdf

Current limitation

• Colibrie only works with text-based PDFs and not scanned documents. (As Tabula explains, "If you can click and drag to select text in your table in a PDF viewer, then your PDF is text-based".)
• For the moment Colibrie doesn't work on PDF with tables that has no structural lines (like this one or this one ) but it can handle a few missing lines (like this one or this one)
