Beautification of Hand-drawn Strokes by Adaptive Moving Average for Illustration Tracing Tasks

Abstract (in Japanese) (See Japanese page) 
(in English) A typical way to draw a digital illustration is first to draw rough line drawings on a paper and then to trace the lines on a graphics-tablet by hand. The input lines usually contain fluctuation due to hand-drawing, which limits the quality of illustration. Although naive applications of moving average filters can smooth input lines, they may cause over-smoothing artifacts in which sharp features are lost by the filtering. This paper describes an improved line smoothing method using adaptive moving averages, which smoothes input lines while keeping high curvature points. The proposed method evaluates curvatures of input lines and adaptively controls the filter-size to reduce the over-smoothing artifacts. Experiments demonstrated advantages of the proposed method over the previous method in terms of smoothing effect with sharp feature preservation.
