Hi all,

Is there an image acquisition node? I would like to import a .tif containing an image of fixed width data and convert to CSV (or similar).

Thanks

Hi,


It might be that someone within the community has looked at developing such a node and you may get a better response than mine...

That being said ....

There are no nodes which perform optical character recognition (OCR) on input image files within Lavastorm shipped libraries (BRGs).

There is an experimental Image File node in the inFlow library.

This does not perform any OCR, it simply reads in the image.
The main aim of this is to read in an image file and then display it in a Visualizer node.

The image format that it brings in is a String with a jpeg mime-type, containing a base-64 encoded JPEG image.

There are 3rd party open source OCR solutions available such as Java OCR (e.g. see http://sourceforge.net/projects/javaocr/).

I think the best way to achieve what you want would be to read the image in using the Image File node.
You could then plug the output of the Image File node into the input of a Java node.
Then, you should just need to put in some code in the Java node to decode the image into a format understood by the 3rd party OCR library & output the data.

It does sound like a good enhancement to be able to handle OCR, so I'll look into seeing if this is an existing enhancement request, and if not create one.

Note: As the Image File node is experimental, the node has not necessarily been fully tested, and no guarantees are made about maintaining backwards compatibility across different versions.

Tim.

Hi Tim,

Where can I find this experimental node?

Kind regards,
Stefan

Hi Stefan,

To enable the Experimental nodes within the BRE client select “Tools” then “Preferences”. On the General Tab select the “Advanced…” button and check the “Use Experimental Nodes” option. A warning notice appears describing the use and limitations of the Experimental nodes - Ok all of the dialogues. The Experimental nodes should now appear in the pallette in their relevant node categories. The Image File node can be found in the Acquisition category.

As stated in the Tim's original post and in the BRE warning dialogue, the experimental nodes are subject to change, replacement or removal in future versions of the product.

Regards,
Adrian
