Is elixir a viable option for developing AR?
https://github.com/cocoa-xu/evision exists. This is bindings to OpenCV, which is really the thing you want for doing AR.

Aspiration for evision (Aspiration for 2022)
I also have an aspiration to apply the Pelemay technology to evision. That is, I'm going to implement optimization invocations of evision.

[Question] How to find affine transformation between contours?
I managed to use the cv2.ximgproc.ContourFitting in cpp instead of python with the help of the demo: https://github.com/opencv/opencv_contrib/blob/3.4.0/modules/ximgproc/samples/fourier_descriptors_demo.cpp

[Question] Easiest way to detect ethnicity using OpenCV & C++?
As the title implies, I'm looking for the simplest way to detect race/ethnicity in a photo (or a frame by frame video, shouldn't big a big difference) using OpenCV (I'm using the opencv-contrib build) and C++. I'm a complete beginner.

HOWTO: Install OpenCV in Raspberry Pi OS (Buster)
git clone https://github.com/opencv/opencv.git git clone https://github.com/opencv/opencv_contrib.git mkdir ~/opencv/build cd ~/opencv/build
What are some alternatives?
When comparing evision and opencv_contrib you can also consider the following projects:
nx - Multi-dimensional arrays (tensors) and numerical definitions for Elixir
zephyr - Primary Git Repository for the Zephyr Project. Zephyr is a new generation, scalable, optimized, secure RTOS for multiple hardware architectures.
