Color segmentation is a challenging subtask in computer vision. Most popular approaches are computationally expensive, involve an extensive off-line training phase and/or rely on a stationary camera. This paper presents an approach for color learning on-board a legged robot with limited computational and memory resources. A key defining feature of the approach is that it works without any labeled training data. Rather, it trains autonomously from a color-coded model of its environment. The process is fully implemented, completely autonomous, and provides high degree of segmentation accuracy.

The St. Louis Chess Club and Scholastic Center has a pretty humble beginning. After retiring and moving back to his Missouri home, financier (and Forbes contributor) Rex Sinquefield had settled into the St. Louis area. A lifelong chess player, Sinquefield told me his motivation for creating his club was pretty simple, "I just wanted a chess club. It thought it'd be nice to have a chess club in St. Louis." Nearly a decade later, the simple desire of a guy who just wanted to play chess in his retirement has turned a neighborhood in St. Louis into a virtual chess campus - complete with a club, a museum, a home for grandmasters, and a chess-themed diner.
