PlanetPress Capture ICR
The term "ICR", which means "Intelligent Character Recognition" is an evolution on the popularly-
known "OCR", which is "Optical Character Recognition". The difference between the two is easily
explained: While OCR can only recognize characters using the finished shape (for example, in scanned
documents and pictures), ICR relies on much more data which is provided by the Anoto Digital Pen: the
path that the pen takes, the exact timing of this path, start and stop points, etc. This extra information
boosts the recognition rates of characters by a wide margin.
It's important to note that both OCR and ICR are relatively loose terms - that is to say, they can have dif-
ferent specific meanings depending on the technology used, but in their general sense mean the same
thing. When using the term ICR, we use the above definition for convenience.
Note: The PlanetPress Capture ICR engine is only available with PReS Workflow version 7.5
and higher.
An ICR Workflow
The ICR engine in PReS Workflow is used in conjunction with PlanetPress Capture, translating the ink
from the Anoto Digital Pen into separate characters, or text, that is readable by the suite. Multiple com-
ponents are required in order for the ICR to work:
l
In PlanetPress Design, a Capture Field Object must be added and the Perform ICR option must
be activated (See the Capture Field page in the PlanetPress Design User Guide). This must be
either a Multi-Area Field or a Text Field.
l
The Capture Fields Processor must have the Perform ICR Recognition option checked, and lan-
guage needs to be selected.
l
Once the ICR data is available, do something with it. This is done by reading the ICR data that is
available in the metadata generated by the Get Capture Document task.
l
The metadata is also readable by the Capture Condition task, including the captured text and the
reliability of this text.
The Workflow as such is the following:
