Abstract: A method is provided for converting a template creation input corresponding to an image into a sketch template. This method may include minimizing stroke data cost and converting the resulting contour into a curve approximation based around landmark points. After the sketch template is created, it may be personalized using various styles which alter the parameters of the curve approximation and/or the landmark points. The sketch template may be used to practice drawing skills. A tracing algorithm may provide feedback as to how far a tracing line deviates from the sketch template, and may also provide overall feedback for all the tracing lines combined, relating to factors such as closeness to the sketch template, speed, and completion percentage.
