Assessing skin hue to skin tone makes measuring biometric bias easier — research

A team of Sony and Tokyo University researchers say they have created a better way to measure apparent skin color in computer vision, a task at the heart of worries that facial recognition algorithms might never grow beyond harmful biases.

In their pre-print paper posted on Cornell University's arXiv server, the scientists say their proposal is a "simple, yet effective, first step towards a multidimensional skin color score."

They have added a skin hue axis – from red to yellow …
