Building a simple medical image segmentation tool in #JuliaLang.

So far the method only creates raw contours. Next I need to add contour cutting, merging, spline based smoothing, growing/shrinking, manual drawing, etc. and before you know it we have a high performance and #opensource tool for medical image segmentation!

I recently posted a demo how to combine plots in Julia with typst (latex is also possible). I now wrote a blogpost on it:

Makie really amazes me with the quality of plots produced out of the box. With some minor tweaking you can generate art with it.

I wrote a long post explaining how I do format my figures for publications, posters and so on., on how to ensure everything looks nice on the paper (or the screen). With tips both for #matplotlib and #makie! Most probably I will have to polish the writing a bit, but here it is, enjoy! https://victorseven.github.io/2024/09/making-graphs #dataviz #julialang #python

New Unfold animations!

Made with #Makie in #Julia and #Unfold.jl

They show simulated #EEG / ERP data of overlapping events (e.g. eye movements) and linear/non-linear modelling of continuous ERP effects (e.g. stimulus-contrast, saccade amplitude etc.)

thanks a ton to the awesome Makie-Team making such animations super easy :)

Working on #julialang code for surface curvature analysis.

This video shows the surface principal curvatures, i.e. the highest (left) and lowest (right) curvature. Directions of curvature are overlaid too.

I like this "mother-child" model as it has flat bits (base), different cylinder-like bits (arms/body), sphere-like bits (heads), and saddle-like bits (e.g. necks). So it is a nice model for curvature analysis.

#opensource #geometryprocessing #Makie

@bradyajohnston Julia based geometry creation, geometry processing, automated design, meshing, and linking with FEA is the broad scope at the moment. I recommend projects like #Makie (and its users in the meshing community) for inspiration https://docs.makie.org.

Interested in 3D models of anatomical parts? I copied this data http://lifesciencedb.jp/bp3d/ to a GitHub repository, and added a rough first pass at a #JuliaLang interface and #Makie visualisation.

GitHub can render the STLs in a browser too e.g.: https://github.com/Kevin-Mattheus-Moerman/BodyParts3D/blob/main/assets/BodyParts3D_data/stl/FMA12521.stl

Added "linear lofting" to create meshes spanning from one curve (blue/bottom) to the next (red/top). This can be done for instance with quads (left), triangles that are "slashed" quads (middle), or isosceles/equilateral triangles (right).

#julialang #Makie

Mesh smoothing is useful for obtaining high-quality mesh representations. However each smoothing technique has its own pros/cons. Here Laplacian and HC-smoothing are compared. Laplacian smoothing (each points moves to average of neighbours) can be too aggressive and lead to local inflation/shrinkage, HC-smoothing aims to avoid excessive shape changes (pushes back to original a bit) and may converge on a stable shape.

STL files give each triangle their own coordinates set. So none of the triangles actually share nodes. So step one, after importing such a mesh, is to merge the nodes. This animation shows vertex normal based "inflation", the left is unmerged, the right is merged.

@koehlerson Impressive library. I''l have to check it out.

FYI Simon's on Mastodon for sure: @sdanisch, and so is #Makie @makie

All of these visualizations were prepared thanks to the fantastic #Makie library @makie

I am a bit late for day 1 of #30daymapchallenge but I did a map of all official parking places according to the city of Jena. This was done in #julialang with #Makie 1/2
