Embodiment Construction
[0025] Such as figure 1 As shown, a single image weakly supervised dehazing method based on prior knowledge and deep learning of the present invention comprises the following steps:
[0026] Step 1. Establish a foggy image training set: Use prior knowledge to collect real foggy image samples {X i=1...N} to carry out preliminary dehazing, and obtain the training sample set of fogged images {X i=1...N ,Y i=1...N}, where Y iRepresents a foggy image with X i The corresponding prior knowledge dehazes the image, and N represents the number of training samples;
[0027] Step 2: Build a weakly supervised dehazing model, the process is as follows:
[0028] Step 201, use convolution, batch normalization and activation function to form a convolution block, after continuous convolution coding, obtain the feature map f of the original input image size 1 / 16 1 / 16 ;
[0029] Step 202, for f 1 / 16 After pooling and upsampling at 1 / 2, 1 / 4, 1 / 8, and 1 / 16 scales, respectively, the features...
