Semi-random funky stuff, mainly for my PhD experiments and articles. Contains calculations and algorithm implementations for various applied mathematics and astrophysics articles I worked on - Solar Dynamics Observatory image processing, sub-pixel image registration, non-convex optimization. Written in C++20, with C++ ImGui GUI and ImPlot / pybind11+matplotlib plots. Uses OpenCV, OpenMP, OpenGL, cuda, matplotlib, torch, astropy, spdlog, flamegraph, fmt, googletest, json, optick, pybind11, QCustomPlot, tracy, glad, GLFW, ImGui. Examples below.
- 📌 Iterative Phase Correlation Algorithm for High-precision Subpixel Image Registration
- 🪐 Measuring Solar Differential Rotation with an Iterative Phase Correlation Method
🔎Subpixel shift / rotation / scale image registration of dissimilar images via Iterative Phase Correlation
☀️Solar photosphere differential rotation measurements from SDO/HMI continuum images
