Embodiment Construction
[0069] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments. Such as figure 1 As shown, the digital image active camouflage technical solution provided by the present invention includes two main stages of adaptive camouflage and original image restoration.
[0070] refer to figure 2 -- Figure 4 , the implementation process of digital image adaptive camouflage is described as follows:
[0071] Step 1: Input the image I to be camouflaged (refer to Image 6 ), and the user key key.
[0072] Step 2: The user selects a polygonal closed area in the image as the target area to be camouflaged through the mouse, and uses the area outside the target area as the image background area (refer to Figure 7 ), and record the target area boundary chain code L.
[0073] Step 3: Extract the luminance components of the RGB colors of the original color image I , to get a grayscale image .
