I am working on a form recognition solution and considered itVision as a tool that can aid in important steps: deskewing and aligning the form to an empty master. Here it is done with openCV so maybe ieVision can do that,too. The keyword seems to be homography:

It would be great if this was doable with ieVision and if someone could supply a hint into the correct direction!

Thanks in advance!

Hi

Homography is not supported yet, but I'll add it to the to-do list.

You might take a look at the demo of S.Petric at:

Supporting homography would surely bing a lot of new customers because commercial specialized libraries for the job of alignment/deskew are too expensive for smaller budget projects (Recogniform, Leadtools).

Do you have an idea about a rough timeline for that feature? I know OpenCV can do it out of the box but I only found Java/c oder Python examples.

Hi Michael

We'll be doing some features for IEVision later in the year, and we'll investigate whether this is practical to implement.

You should also request it on our user voice page:
