Abstract

The subject of this paper is to read CARPET PATTERN automatically by computer. This is composed of two steps: detection of vertical and horizontal lines in the pattern and COLOR REDUCTION. COLOR REDUCTION is essential because of limitation of the number of colors that is used in a carpet.To accomplish of this process, we must detect the grid lines on the CARPET PATTERN automatically. These lines are two types: thin lines and thick lines. At the first stage, the distance between thin lines is obtained. Having the first thin line detected, the other thin lines are drawn using this distance. We use a Comb method for detection of thick lines. The major problem in line detection is lagging or leading of the lines due to the mismatch between sampling frequency of the scanner and image resolution. We compensate this distortion in various steps in our algorithm.In the second step, we want all the pixels in the same square, to have the same color. This is obtained by mapping colors to the best color in the palette. We propose three methods. In first method the user selects two selections per any colors. Palette is obtained from some processes in these selections. Those pixels that are in the middle of the squares are mapped to the palette. Then color histogram is computed. The color that has the maximum histogram value is assigned to the square. In order to decrease user’s interference, C-means clustering algorithm is used in two types. The centers of initial clusters are determined once with user’s interference and once randomly. Results of these three methods are compared.We tested our methods on 20 samples of CARPET PATTERNs, and the error rate was variable from 0.07% to 0.5% between samples.
