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.

Description

technical field [0001] Embodiments of the present invention relate generally to interactive sketch template technology, and more particularly, to methods, apparatus, and computer program products for creating, changing, and using image-based interactive sketch templates. Background technique [0002] Whether for professional or recreational reasons, the ability to draw well has become an important part of one's abilities. One way to improve your drawing ability is sketch stencil tracing. This allows one to track and get a template to compare to the finished painting. Sketch tracing can be performed mechanically using a printed sketch template and a pencil or other writing implement. [0003] However, mechanical sketch tracking has some disadvantages: the sketch template can usually only be used once. Sketch templates also cannot be easily modified. Furthermore, there are a limited number and types of sketch templates available for printing. Finally, there is no formaliz...
