Generating method for digital disguise image

Abstract

The invention discloses a generating method for a digital disguise image. The method includes the following steps: selecting a disguise area in a foreground image, and placing a background image in the disguise area; conducting second-scale decomposition processing on the disguise area and the background image; conducting edge extraction and structure edge recognition on the disguise area to obtain important structure characteristic edges; conducting expansion and subsection processing on a long edge in the important structure characteristic edges to obtain a non-continuous structure important edge restrain mapping picture; defining gradient restrain of large-scale layer gradient of the disguise area; according to the structure important edge restrain mapping picture and the gradient restrain, conducting non-linear integration on large-scale layers of the disguise area and the background image; mixing a detail layer of the disguise area and a detail layer of the background image; and overlaying the large-scale layer of a result image and a detail layer of the result image, and combining a color channel of the background image to obtain the disguise image. The generating method for the digital disguise image is explicit in arithmetic, friendly in interface, and vivid in results.

Description

technical field [0001] The invention relates to the technical field of computer image processing, in particular to a method for generating a digital camouflage image. Background technique [0002] Camouflage imagery is a typical optical illusion entertainment art, which is very special and charming. One or more objects are usually hidden in a camouflaged image. When people observe this type of image, they usually perceive the main features of the entire image first. However, after observing the scene features more carefully, people usually recognize the scene. other objects are hidden. [0003] Realistic camouflage images are usually created manually by artists. The artist first outlines the entire image scene and the structural lines of the hidden object, and then continuously adds texture details on this basis to achieve the effect of hiding the object. Similar to the artist's creative process, in the drawing of camouflage images, we separately deal with the structural l...
