Vector reps will be important for future display technology. Hoppe and Forsyth do excellent work.
IEEE CS TVCGVector graphics has been employed in a wide variety of applications due to its scalability and editability. Editability is a high priority for artists and designers who wish to produce vector-based graphical content with minimal user interaction. In this paper, we introduce a new vector image representation based on piecewise smooth subdivision surfaces, as well as techniques based on this representation to support a variety of editing operations, including image object deformation, color editing, image stylization, and vector image processing. These operations effectively create novel vector graphics by reusing and altering existing image vectorization results. Because image vectorization yields an abstraction of the original raster image, controlling the level of detail of this abstraction is highly desirable. To this end, we design a feature-oriented vector image pyramid that offers multiple levels of abstraction simultaneously. Our new vector image representation can be rasterized efficiently using GPU-accelerated subdivision. Experiments indicate that our vector image representation achieves high visual quality and better supports editing operations than existing representations.
