Texture matching of a sample is one of the important factors for blending in with their surroundings. It has long been debated that which of the colour-texture matching of the background, matching strategy, or disrupting the shape of a sample, disruption strategy, is more important for hiding a sample in an environment. Previouse researches based on the human visual knowledge have shown that detection is mainly influenced by the matching strategy and recognition is affected mostly by the disruption strategy. It is believed that the traditional patterns designed for hiding out in an environment is not effective enough, due to the fact that the boundary of the blobs of the patterns are smooth. This research is focused on designing the texture of the pattern in a way that it merges in the chosen background more effectively than the traditional patterns. To do so, six images of target area with different fractal surface characteristics were chosen and considered as backgrounds for psychophysical experiments and they fractalised in gray scale via fourier transfer technique. Using fourier transfer technique, the ? value, which is often used as a mathematical measure of image texture and its perceptual correlates that has a linear relationship with fractal dimension of the image, is calculated. Then, an artificial power spectrum (P) is obtained by applying the ? value in an appropriate formula. A new amplitude and phase spectrum is calculated by the P value, and finally a new fractalised image is obtained by an inverse fourier transfer technique. The colour of the fractalised images then reduced in four colour by a k - means method and digitalised. Employing a characterised LCD a photo simulation experiment was made and by conducting of two different psychophysical methods, detection and priority techniques, twenty - four observers with normal vision assessed the hiding efficiency of the three patterns, fractalised pattern, fractal colour reduction digitalised pattern and traditional pattern or non-fractalised pattern. In detection psychophysical experiment the observers were asked to click on the patterns if they manage to see them. In this experiment, the patterns had been randomly shown on the different locations of the backgrounds and the average of the detection times were recorded by the program. In the priority psychophysical experiment, the three patterns were displayed on each the backgrounds simultaneously and the observers were asked to sort them on the basic of their capability of blending in with their background. In the detection psychophysical experiment, in few cases it seemed that the observers detected the patterns in a way which did not follow the general conclusion of the research, i.e. the fractalised patterns due to having the same fractal dimensions with their backgrounds are the best. Further research on these cases showed that for them the surface characteristics of the fractalised patterns and one for the exact area of the backgrounds, where the patterns lie on, were very different and therefore, the general conclusion of the research has not been violated.
