Notes
Up to this point, we've been concerned with understanding and building features of strokes and using these features to describe and classify gestures. With that background on machine learning and the familiarity gained with working on sketch data, we are now moving into more sketch-specific problems. To begin with, we will look at corner detection for a few readings. One of the more important original works in corner detection also helps to communicate the intuition behind the features that are often used, so we will be starting with the Sezgin/Stahovich paper shared in the class drive.
