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, and others. 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
📉Visualization of optimizer progress on a given objective function landscape
📈Visualization of meta-optimizer progress and optimization improvement on a given meta-objective function landscape
📊Adaptive histogram equalization
⌚Profiling with Tracy
- install the required libraries
sudo apt -y install libglfw3-dev libgtk-3-dev libcapstone-dev libtbb-dev
- build the profiler via
make release -j12
in./libs/tracy/profiler/build/unix/
- run the app with
ENABLE_PROFILING
defined - run
script/perf/tracy.sh
or./libs/tracy/profiler/build/unix/Tracy-release
and click connect - save the trace file if needed
