Hi ,
we are trying to extract only specific information from Unstructured scanned pdf document,But the pdf doc will be dynamic format.
One document will come in one format but other will come in different format.But only few changes in body of the pdf paragraph.
for example,out of 3 pages Doc,we will extract only first page necessary information.
Using Electroneek is it possible ?Please help us.
