You initialize once, process many images in a loop, and terminate once. For the truly geeky, click here for a complete description of the TeraForm API innards . If you want TeraForm to handle both the zoning and OCR, you can call a special API we've created which invokes both TeraForm and PrimeOCR in succession with just one set of function calls. We get asked that a lot. Unfortunately, there is no quick answer - it depends on the task.
Some engines are more suited to specific tasks and font types than others.
One of the advantages of using TeraForm is that we can run your sample set through many different OCRs and let you know which ones do well. You can then stay at the forefront of OCR technology by simply replacing the OCR engine as new ones become available. Inc. All rights reserved.
