Smooth Outline Tracing using Fuzzy Reasoning

Abstract

We introduce a making method of "Edge image data like rough sketch" for the smooth outline tracing using fuzzy reasoning and examine it. This method was based on the sketch technique that man draws the rough sketch. At first, the edge of the car is detected from the input image using Sobel operator. Next, the edge is divided in the section where curvature is nearly. Finally, the edge was drawn many short and straight approximation lines by the least square method. Thus image data with values of degree that seems to be outline is made. In experimental results, most output images were nearly equal to the outline of input images.
