Generate Natural Stroke
We used a real photo as a reference in order to generate natural and smooth strokes. By far, this was the most challenging part of the project. We knew that some of the common approaches to robotic art include 1. Painting with dots 2. Using straight lines (just like in printers) and 3. Using very small strokes on a big canvas.
Our goal was to capacitate the robot to draw natural and long (or short when necessary) strokes, just like a real human being. Therefore, we developed an original technique called Deep Stroke Line (DSL), which is able to automatically generate a trace of a natural human-like stroke line. Please take a peak to our video, where you can see the process of how our technology generates natural strokes.
