3 Generation of Cartoon Blur We analysed the above elements to establish the data and parameters necessary to express cartoon blur. From further analysis, Fig.2 shows the outline method for generating cartoon blur. Firstly, we select the face which is required to generate the cartoon blur. Secondly, we prepare two processes that relate to the target face. One process detects the rear edges whilst the other process generates each cartoon blur. The segments which form the cartoon blur comprise the edges on the rear side of the object. The algorithm detects these rear edges from the given input face data.
