As an AI language model, I do not have the full context of your code. However, this error seems to indicate that there is an issue with the rof.denoise() function. It is possible that the function is not properly defined or that there is an issue with the input parameters. Without more information, it is difficult to provide a more specific solution.

ModuleNotFoundError: No module named 'rof'
很抱歉,根据提供的引用内容,我没有找到关于"rof"的信息。"ModuleNotFoundError: No module named 'rof'"的错误提示通常是由于缺少相应的Python模块导致的。您可以尝试检查拼写是否正确或者查看您的代码中是否有导入该模块的语句。如果您确定该模块存在但仍然出现此错误,请尝试重新安装该模块或者检查您的Python环境配置是否正确。
ROF算法 matlab完整代码
下面是ROF算法的Matlab完整代码:
```matlab
function u = ROF(f, lambda, tau, epsilon)
% ROF算法实现
% 输入:原始图像f,正则化参数lambda,步长参数tau,停止条件epsilon
% 输出:去噪后的图像u
% 初始化
u = f;
[height, width] = size(f);
delta = zeros(height, width, 2);
while true
% 梯度计算
grad_u = grad(u);
normDu = sqrt(sum(grad_u.^2, 3));
% 更新delta
delta(:, :, 1) = delta(:, :, 1) + tau*grad_u(:, :, 1)./repmat(normDu + epsilon, [1 1 2]);
delta(:, :, 2) = delta(:, :, 2) + tau*grad_u(:, :, 2)./repmat(normDu + epsilon, [1 1 2]);
% 更新u
u = (u + lambda*div(delta))./(1 + lambda*sqrt(sum(delta.^2, 3)));
% 判断停止条件
if norm(u - f, 'fro')/norm(f, 'fro') < epsilon
break
end
end
end
% 梯度计算
function Du = grad(u)
[height, width] = size(u);
Du = zeros(height, width, 2);
Du(:, :, 1) = circshift(u, [0 -1]) - u;
Du(:, end, 1) = 0;
Du(:, :, 2) = circshift(u, [-1 0]) - u;
Du(end, :, 2) = 0;
end
% 散度计算
function div_u = div(u)
[height, width, ~] = size(u);
div_u = zeros(height, width);
div_u(:, 2:end) = u(:, 2:end, 1) - u(:, 1:end-1, 1);
div_u(2:end, :) = div_u(2:end, :) + u(2:end, :, 2) - u(1:end-1, :, 2);
end
```
其中,grad函数计算图像的梯度,div函数计算图像梯度的散度。
