Hi Johannes @jo-mueller ,

super cool new slides!

• One question about the the thresholding slide: If I remember correcty, the left panel shows the Triangle method, the other two show Otsu, right? I'm asking, because I find the arrangement confusing. It appears these three panels explain Otsu...

• On this slide, I think it would be cool to draw an example for Semantic Segmentation:

• The last slide looks like this. You may at least add a summary slide:

• Please remove my twitter handle from your slides. Feel free to put your own twitter handle.

Regarding the notebooks: I like them a lot! Many nice exercises.

• If there is time, you could put some more links into the notebooks, e.g. if you mention Otsu's threshold method (Otsu et al., IEEE, 1979).

• Consider replacing key1 and key2 with Number and Weekday in this notebook. This highlights the importance of descriptive variable names / table column headers.

• Last but not least, please add yourself to the list of authors / copyright holders in the readme,

And feel free to merge afterwards. The students should not need to wait for another approval.

Thanks!

Best,
Robert

Hi Johannes @jo-mueller,

The slides look great to me! Also the notebooks really relate to the slides in a good manner! I am looking forward to the lecture!!

My only suggestion, if you think there is time for that, is to briefly recap the plt.subplots.

Robert had a good slide for that, which I put last in my pdf for students to have as a reference, but I didn't have time to explain it well (I explained during the exercises/notebooks part, but not as part of the talk). You could just use that one IMO.

Best,
Marcelo
