ChemInk

Project Lead: Tom Ouyang

ChemInk is a new sketch recognition framework for chemical structure drawings that combines multiple levels of visual features using a jointly trained conditional random field. The result is a recognizer that is better able to handle the wide range of drawing styles found in messy freehand sketches. A preliminary user study also showed that participants were on average over twice as fast using our sketch-based system compared to ChemDraw, a popular CAD-based tool for authoring chemical diagrams.
