A SURVEY ON CONTINUOUS LINE ILLUSTRATION DEVELOPMENT FROM SKETCHES OR IMAGES

Continuous line illustrations (CLI) consist of a single line in a sketch that is drawn without lifting our drawing aid from the surface until the work is completed. For the given input sketch first, detect the edges, and using this edge we can perform the joining of the curves. After identifying the curves according to their priority they get connected by using some predefined rules and thus obtainedthe CLI. Even though the area of CLI is not well explored, many researchers are curious about how to discover more features under computer graphics. Most works in this area already have many flaws. To reduce these flaws many methods are developed to develop CLIfrom sketches and images.
