基于SRCNN深度神经网络的超分辨率重建算法的matlab仿真-源码
当然可以,以下是一个简单的MATLAB代码示例,使用深度循环神经网络(RNN)实现超分辨率(SR)感知。
```matlab
% 训练集和测试集
load('SR_data.mat');
X_train = LR_train;
Y_train = HR_train;
X_test = LR_test;
Y_test = HR_test;
% 超参数定义
num_epochs = 50;
batch_size = 16;
learning_rate = 0.001;
hidden_size = 128;
num_layers = 3;
input_size = size(X_train, 2);
output_size = size(Y_train, 2);
% RNN模型定义
model = rnn(hidden_size, num_layers, input_size, output_size);
% 损失函数和优化器定义
criterion = nn.MSECriterion();
optimizer = optim.SGD(model:getParameters(), learning_rate);
% 开始训练
for epoch = 1:num_epochs
% 每个epoch重新打乱训练集
random_indices = randperm(size(X_train, 1));
X_train = X_train(random_indices, :);
Y_train = Y_train(random_indices, :);
% minibatch训练
for i = 1:batch_size:size(X_train, 1)
local_batch_size = math.min(batch_size, size(X_train, 1) - i + 1);
local_X_train = X_train(i:i+local_batch_size-1,:);
local_Y_train = Y_train(i:i+local_batch_size-1,:);
-- 前向传递和计算损失
outputs = model:forward(local_X_train);
loss = criterion:forward(outputs, local_Y_train);
-- 反向传递和更新参数
gradOutputs = criterion:backward(outputs, local_Y_train);
model:backward(local_X_train, gradOutputs);
optimizer:updateParameters(learning_rate);
end
% 训练集和测试集上的评估
train_loss = criterion:forward(model:forward(X_train), Y_train);
test_loss = criterion:forward(model:forward(X_test), Y_test);
fprintf('Epoch %d, train_loss: %f, test_loss: %f\n', epoch, train_loss, test_loss);
end
% 预测SR图像
Y_pred = model:forward(X_test);
```
需要注意的是,这只是一个简单的示例代码,你需要根据自己的数据和具体任务进行修改。此外,使用深度循环神经网络(RNN)实现超分辨率(SR)感知可能不是最优的选择,你可以考虑使用其他模型和算法。
