Embodiment Construction
[0066] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0067] figure 1 It is a flowchart of a method for removing rain from a single image of a UAV based on a convolutional neural network provided by an embodiment of the present invention. Such as figure 1 Shown, the UAV single image based on convolutional neural network of the present invention removes rain
[0068] method, including the following steps:
[0069] S1, separating the rainy image into a low-frequency background image and a high-frequency rainline image through a guided filter;
[0070] S2, using a multi-scale CNN convolutional neural network to perform sub-channel feature extraction on low-frequency background images and high-frequency rainline images;
[0071] S3, reassign weight...
