  • When I segmented 3D MRI and CT scan images before I used the contrast borders for help a lot. There were some algorithms for finding edges that you could tune by setting search radiuses and thresholds. There was also an option of growing an area by a certain amount of pixels outward, and then threshholding the result back down to only the brighter parts, that kind of thing. You had to be a little clever about how you’d combine it. And ultimately, sometimes I just had to add and subtract a few points manually.

    Segmenting is more assigning areas to distinct objects (separating bones from the rest in my case), but you could totally use it as a basis for coloring, so I assume the process is similar here.












  • Ah that’s interesting, thanks.

    Here in Switzerland if a shift is longer than 5.5 hours it needs to have at minimum 15min unpaid break for lunch by law. Longer than 7 hours means 30min unpaid lunch and longer than 9 hours means an hour unpaid lunch by law. Additionally if the split is uneaven such that the period before or after lunch is over 5.5 hours, then you recursively get another break following the above rule by law. But these are all unpaid and do not count as hours worked.

    The usual reality for typical 8.2 h/d office jobs is that people take half an hour to an hour of lunch, unpaid, and companies allow two 15 min paid coffee breaks, one in the morning, one in the afternoon, despite not being forced to by law.
