Inspiration

I like startrail photography but find it takes too long time to take. While the changing elements in the image take very small portion.

What it does

The program requires a foreground image then generates customized startails on the background sky.

How I built it

I wrote the program in Mathematica and use iOS device to upload image and pull back products.

Challenges I ran into

Server availability. Network connection stability.

Accomplishments that I'm proud of

The graphical function side works great and the product images looks like real startrail photos.

What I learned

Communication between server and client.

What's next for startrail photography simulator

Extract real stars' position using computer vision algorithms. Predict the realistic trajectories by their moving trends.
