WIP: Update notebooks for EuroSciPy 2022

[lagru]

Addresses some deprecation in and before v0.19 as well as other (minor) updates. We plan to use the lectures 00_images_are_arrays, 1_image_filters and 4_segmentation so these are mainly tested and addressed here. Agenda below:

• [ ] lectures
  • [x] 00_images_are_arrays circle -> disc
  • [x] 3_morphological skdemo.imshow_all(image, morphology.erosion(image, sq), shape=(1, 2)) AttributeError: 'AxesImage' object has no property 'shape'
  • [x] 4_segmentation DeprecationWarning: np.int
  • [ ] 4_segmentation UserWarning: The probability range is outside [0, 1] given the tolerance prob_tol. Consider decreasing beta and/or decreasing tol.
  • [ ] 4_segmentation active_contour doesn't really fit head
  • [x] 5_tophat FutureWarning: selem is a deprecated argument name for closing. It will be removed in version 1.0. Please use footprint instead.
  • [x] 6_watershed FutureWarning: selem is a deprecated argument name for dilation.
• [ ] solutions
  • [x] 00_images circle -> disc
  • [x] 1_images_filters ConvergenceWarning: lbfgs failed to converge (status=1): STOP: TOTAL NO. of ITERATIONS REACHED LIMIT.
  • [x] 1_images_filters "Take a look at this neat feature merged last year:"
  • [ ] 4_segmentation active_contour doesn't really fit head
• [ ] check_setup.py fails with ValueError: not enough values to unpack (expected 3, got 1) because new dependencies got added for the jupyter-book stuff -> clashes with tutorial

Hey @emmanuelle, thanks for taking a look at the already included fixes and updates. However, this wasn't yet complete. I think I forgot to mark this as WIP via GitHub's interface. There are still open issues with

• 4_segmentation UserWarning: The probability range is outside [0, 1] given the tolerance prob_tol. Consider decreasing beta and/or decreasing tol.
• 4_segmentation active_contour doesn't really fit head

We already talked at the meeting about the second point but I haven't looked to deply into the UserWarning yet. I will continue this in a new PR.
