I recently was reviewing ImageCorners.jl and it uses imgradient a lot, and there exist of lot of different types of filter like prewitt, sobel etc that are utilized. I would wanna introduce readers to…

Time-like paths recorded as a set of finite differences can be converted into a list of displacements.
These will always have a monotonic t(tau) and thus efficient methods can be used to display pre-r…

I would suggest moving the following tools to the `Applications` module while renaming and possibly extending them as follows:
- [ ] `calculate-filtering` -> `calculate-local-image-statistics`.
- [ ] …

On GPU, prtcB-flat-r3_cxx_vs_f90 is still not BFB with the Fortran on CPU. Differences are strongly suggestive of error from finite precision. Could be a gfortran CPU vs nvcc GPU thing, or could be de…

`ngradient` implements a version of Finite Differences Method like that provided by
[JuliaDiff/FiniteDifferences.jl](https://github.com/JuliaDiff/FiniteDifferences.jl). The numerical gradient checki…

# Wave on a string
Simulation involving propagation of transverse waves on ideal strings. It can demonstrate reflection off hard boundaries and open ends, as well as a junction of strings with differ…

In the function `outward_normal` in `render.py`, when `method == 'finite_differences'` the gradient is calculated by `tetrahedron` algorithm.
This is suitable for SDF, but how about Occupancy Functio…

Comparison operators are very bad for autodiff because they admit the construction of discontinuous functions. Equals operators are particularly bad because they can't even be tested with finite diff…

DynamicHMC does not deal well with incorrect deriatives. These can result from AD errors (conceptual errors in mature AD libraries are rare, but numerical corner cases can still happen), or bugs in ma…

There's a lot of nuance behind how one decides to discretize in z. For example, in the microlens array example, the structure is sliced such that the upper corner of each slice lies right on the ideal…
