Multi-background camouflage pattern main color extraction method based on color relevancy

Abstract

The invention discloses a multi-background camouflage pattern main color extraction method based on color relevancy, and mainly solves the problem that it is difficult for an existing camouflage pattern main color extraction method under a single background to meet the multi-background multi-region camouflage requirement. The method comprises the following steps: s1, selecting a plurality of background images of a to-be-camouflaged area, and carrying out image preprocessing; s2, extracting the background main color of each background image, and calculating the area proportion of the backgroundmain color; s3, performing priority ranking on the background main color of each background image, and listing ranked search paths; s4, selecting a search path according to the color relevancy measurement function, and carrying out background main color pairing; and s5, performing main color calculation on a background main color pairing result to obtain the final area ratio of the main color tothe main color of the multi-background camouflage pattern. The method is low in calculation complexity and high in real-time performance, the fusion degree of the extracted camouflage main color and the extracted background color is high, and the requirement for accurate main color extraction of multi-background camouflage pattern design in a large-area dynamic environment can be met.

Description

technical field [0001] The invention relates to the technical field of image processing and analysis and camouflage camouflage design, in particular to a method for extracting main colors of multi-background camouflage patterns based on color correlation. Background technique [0002] Camouflage camouflage is one of the most convenient and effective military camouflage protection methods. It can be applied to various military targets such as personnel, clothing, weapons and equipment, and position engineering. It has been widely used in the armies of various countries. At present, the research on camouflage pattern design method mostly focuses on the generation of single background camouflage pattern. The design method is relatively mature and has been applied to many combat equipments, which can achieve better camouflage effect. However, when the camouflage target is in a large-area multi-background (complex background) environment, the existing single-background camouflage...
