40-Year Math Error Fixed: 16x Faster Computer Vision Algorithm

RANSAC, a popular computer vision algorithm, had a 40-year math error that made it 16x slower than needed. A simple fix corrected the formula, reducing iterations without affecting result quality.

  Overview

RANSAC is a popular algorithm for geometric model estimation, but its standard stopping criterion is mathematically flawed
The paper identifies and fixes a fundamental error in the RANSAC stopping criterion formula
The corrected formula leads to significantly fewer iterations needed (up to 16× reduction)
Improvement works with all RA...
