Cant detect a pattern

[p1r473]

I am trying to anonymise a document for printing
I cant seem to detect my pattern
Ive tried printing my calibration test page and scanning it many times, with bmp tiff and png. Ive tried 300 600 1200 dpi. Ive tried all sorts of margins. No matter what I do I cant detect the pattern

I am able to zoom in on my image and indeed see the yellow marks with my own eyes
I am also able to detect the tracking dot with deda_extract_yd Detected tracking dot pattern

Is there any way to turn a unknown pattern into a recognized pattern @timojuez

Yeah, its depressing, I scanned at 1200 and the yellow dots are clear as day, yet the program just cannot seem to find them. No idea what I did wrong.

Hi guys,

first, I wonder about the filename /home/pi/deda/deda_bin/deda_anonmask_create_img.py. It should be deda_anonmask_create in our repository. Anyway, it looks like Deda doesn't recognise a pattern. It must be one of the supported ones by Deda. Do you know, which pattern the printer is using? If you like, send me a picture.

@timojuez Here's the scan, along with a screenshot.
