circle_fit_demo

Compact MATLAB demo for fitting circles and ellipses to noisy pupil-boundary samples (useful for pupil localization / gaze tracking).

This repository contains a single script, circle_fit_demo.m, which generates synthetic examples of boundary samples (full noisy circle, a projected circle that becomes an ellipse, and a partial arc with outliers) and demonstrates three fitting methods:

• Algebraic least-squares circle fit (closed form)
• Geometric nonlinear ciarcle fit (minimizes radial residuals with fminsearch)
• Direct least-squares ellipse fit (Fitzgibbon et al.)

DigitalOcean does not provide a way to download a snapshot of your droplet locally. You can use rsync to accomplish this instead.

On your local machine, assuming you have added your-server in your SSH config:

rsync -aAXHv --append-verify --exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} your-server:/

• -a : archive mode (all files, with permissions, etc.)
• -A : preserve ACLs/permissions (not included with -a)

Long Running Sequences of legal US Postal codes

Pseudo-Compressed Zip Code table. Any 5 consecutive numbers in these sequences are legal US Zip (postal) codes. This is helpful for building dummy data in databases.
