Embodiment Construction

[0067] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0068] combine figure 1 As shown, the digital camouflage pattern generation method based on image fractal texture comprises the following steps:

[0069] s1. Extract the background main color of the background image and the area ratio of the background main color

[0070] In the embodiment of the present invention, based on the layer-by-layer K-means clustering algorithm of the pyramid structure, the background main color of the background image and the area ratio of the background main color are extracted, and the general steps are as follows:

[0071] s1.1, color space conversion

[0072] The Lab color space is a uniform color space with a wider color gamut than RGB and more colors that can be represented, so the background image is converted to the Lab color space;

[0073] s1.2, downsampling Gaussian pyramid model

[0074] The down-sampl...

Abstract

The invention discloses a digital camouflage pattern generation method based on image fractal textures; the method comprises the following steps: s1, extracting a background main color of a backgroundimage and an area proportion of the background main color; s2, forming texture images via improved fractal Brownian motions; s3, colorating the texture images; s4, amplifying the initial camouflage pattern image according to unit dimensions; s5, converting the amplified camouflage pattern image into a camouflage vector image. The method introduces standard deviation corrections in s2 so as to prevent the formed texture images from getting discretization, adds the colorating method in s3, i.e., uses the mixed colorating algorithm to colorate the texture images, and vectorizing the images in s5, thus enabling the camouflage patterns to reach zoom unchanging effect. The method can design camouflage patterns with a strong randomness, adaptability and camouflage effects via a solidification texture image generation step, an optimization texture pattern generation algorithm and an improved coloration algorithm.

Description

technical field [0001] The invention belongs to the technical field of image processing and analysis and camouflage camouflage design, in particular to a digital camouflage pattern generation method based on image fractal texture. Background technique [0002] Digital camouflage is a new generation of camouflage camouflage that comprehensively uses advanced technical means. It is based on the characteristics of human's visual psychological perception of graphics, the characteristics of digital imaging dot matrix, and the characteristics of human vision for target recognition. presented in the form. [0003] The current main methods of camouflage design are divided into manual work and computer intelligent design, among which: [0004] Manual work is that designers design camouflage patterns in drawings or computer-aided design software based on personal experience. This method has the disadvantages of time-consuming, low efficiency, and similar designs. At the same time, i...
