Abstract: In this paper, a series of novel patterns were designed by employing fractal algorithm, such as Julia sets, Koch iteration. At the same time, a spectral reconstruction processing was carried out for those patterns and different textiles by taking advantage of computer image processing technology, so as to simulate the effect of textile laser concave-convex engravings. The results of simulation proved the feasibility and applicability of the algorithm. This technology could not only save costs, but also embody a perfect combination of art and science. New and original, it is of great practical value.
