Quality assessment of fractalized NPR textures: a perceptual objective metric

Texture fractalization is used in many existing approaches to ensure the temporal coherence of a stylized animation. This paper presents the results of a psychophysical user-study evaluating the relative distortion induced by a fractalization process of typical medium textures. We perform a ranking experiment, assess the agreement among the participants and study the criteria they used. Finally we show that the average co-occurrence error is an efficient quality predictor in this context. CR Categories: I.4.7 [Image processing and Computer Vision]: Feature Management—Texture
