Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see (crypsis), or by disguising them as something else (mimesis). Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings. A third approach, motion dazzle, confuses the observer with a conspicuous pattern, making the object visible but momentarily harder to locate. The majority of camouflage methods aim for crypsis, often through a general resemblance to the background, high contrast disruptive coloration, eliminating shadow, and countershading. In the open ocean, where there is no background, the principal methods of camouflage are transparency, silvering, and countershading, while the ability to produce light is among other things used for counter-illumination on the undersides of cephalopods such as squid. Some animals, such as chameleons and octopuses, are capable of actively changing their skin pattern and colours, whether for camouflage or for signalling. It is possible that some plants use camouflage to evade being eaten by herbivores.

Camouflage animal detection method based on frequency domain decoupling and edge information fusion
The invention provides a camouflage animal detection method based on frequency domain decoupling and edge information fusion, relates to the technical field of image processing, and uses an image frequency domain decoupler to dynamically separate low-frequency (global structure) / high-frequency (edge details) features through a learnable Gaussian filter bank so as to obtain a camouflage animal detection result. And the method is efficiently used in an edge contour predictor and a camouflage target detector, so that the detection precision of the camouflage animal is effectively improved. In a high-frequency edge fuzzy scene such as a dead leaf butterfly scene, the target contour response is enhanced by a high-frequency path, and the omission ratio is remarkably reduced; and a low-frequency path reserves the overall form of the target, and the recognition robustness of large-scale camouflage targets such as zebra groups is improved. Meanwhile, under the interference environment of rain and fog / night and the like, the influence of the noise of the sensor on the frequency domain characteristics is small, and the mode of replacing multi-modal data through frequency domain decoupling enables the detection performance to have high detection precision and stability.

A camouflage animal detection method based on frequency domain decoupling and edge information fusion
The application provides a camouflage animal detection method based on frequency domain decoupling and edge information fusion, and relates to the technical field of image processing. The application uses an image frequency domain decoupler to dynamically separate low-frequency (global structure) and high-frequency (edge details) features through a learnable Gaussian filter group, and efficiently utilizes the features in an edge contour predictor and a camouflage target detector, thereby effectively improving the detection accuracy of camouflage animals. In high-frequency edge blur scenes such as dry leaf butterflies, the high-frequency channel enhances the target contour response, and the missing detection rate is significantly reduced. The low-frequency channel retains the overall shape of the target, and improves the recognition robustness of large-scale camouflage targets such as zebra groups. At the same time, in interference environments such as rain, fog and night, the frequency domain features are less affected by sensor noise. By replacing multi-modal data with frequency domain decoupling, the detection performance has high detection accuracy and stability.
