During model training, the input image size was set to 640 × 640, and the Stochastic Gradient Descent (SGD) optimizer with momentum was used. The initial learning rate was set to 0.01, the momentum parameter was set to 0.937, the weight decay coefficient was set to 0.0005, and the batch...
The SSRN network extracts spectral and spatial features through continuous spectral and spatial residual blocks, respectively, effectively alleviating the gradient descent phenomenon. Compared to traditional methods, it has shown significant improvement. Our proposed method further improves the accuracy by ...
