Hello,

I am using LeadTools v17. and the .NET class library with framework 4 (visual studio 2010).

We would like to develop an scanning application for large batches of images. We need a separation feature that creates a new image file each time it is detected a separator page.

We have to define the better way to make a separator page, so my question is:

What would it be faster for the scanning process? A separator page with barcode? A separator page with specific words in specific places? A separator page with a Logo Image and then use Correlation method to compare images? The blank page separator is a bad choice we think.

It would be wonderfull if you could send us a sample project (preferably in .Net 4) using any of the separator methods mentioned above. We are also very worried about performance so, if the example shows how to use scanning in thread and/or using all processors of CPU it would be nice.

Thnks very very much in advance,

Pablo L.G.

Pablo,

I recommend using specific words in specific places because you are already going to OCR the page. Other options like correlation will require extra process.

The only way to access the Pro OCR engine twice from the same process is to use the thunk server. For details, see this page:

Please check our "OCR Multi Threading" demo shipped with the toolkit.
