Frequency domain enhancement-based camouflage object detection method

The invention provides a frequency domain enhancement-based camouflage object detection method, which comprises the following steps of: 1, constructing a camouflage object network: constructing a camouflage detection camouflage object network, inputting an image set of a camouflage object into the camouflage object network, and optimizing the camouflage object network by iteratively optimizing a loss function; 2, constructing a feature alignment module and a high-frequency channel selection module: achieving the purposes of time-frequency feature alignment and high-frequency feature screening by using a disguise object network; 3, dividing the disguise object network framework into a model training stage and a test stage; in the model training stage, a camouflage object training picture set subjected to data preprocessing is input into a camouflage object network, and the camouflage object network is optimized by utilizing a frequency domain enhancement module and twice supervision; and in a test stage, input
