How To Text extract Image in Knime

[omeralitopal]

Hi,

I want to extract from image.

For example, below the picture extract to “artificial intelligence”

I found Tess4J-3.4.8 but how to install in Knime.

Thanks

Hi,

You can install the Tess4J node from the Image Processing and Analysis section of the 3.6 community contributions site (http://update.knime.com/community-contributions/3.6). This bundles its own version of Tess4J, so you don’t need an external version (but I think the node allows you to use an external version if you like).

Kind regards

James

PS dragging and dropping your JPG onto a blank workflow (configures an Image Reader node) and then using the Tess4J node with default settings does a reasonable job but I expect some preprocessing could help)

Hi James,

Thanks for answer but your shared link does not open
And I have Knime 3.6 bur Tess4j not exist.

So Knime all extentions download. Unfortunately Tess4j Node does not exist in Knime 3.6 .

Hi,

Sorry - I should have been clearer… You should choose “Help->Install new software”, and then click the “Add…” button. This will allow you to point to a new repository.

A pop-up will appear where you can type a name (like “Community contributions”), and then enter a URL - that’s where the link I gave should go (http://update.knime.com/community-contributions/3.6).

Now you will be able to choose this new repository in the dropdown of the Available Software interface and find the Tess4J item.

Kind regards

James
