Application of three-dimensional convex analysis in pattern painting camouflage detection

Edge detection is one of the important means to camouflage detection,but the previous edge detection algorithm can not detect the camouflaged targets with three-dimensional convex properties.Thus the operator of the camouflaged targets detection based on the convexity was proposed,which can get an infinite value as response to the convexity.A smoothing filter of the spatial domain was used to preprocess the images in the camouflaged targets detection because of the operator's intense sensitivity to the noise.By testing of real camouflaged scenes,the improved method was improved to be effective to detect and recoginze the targets under strong camouflage by using the difference of the gray-scale represented by the characteristics of 3Dconvex shape.
