所有算法的策略模式和迭代器

[英]Strategy pattern and iterator on all algorithms

I have a list of algorithms that I want to run on an image for denoise it. 我有一个要在图像上进行去噪的算法列表。 I have several different algorithms for denoising my pics. 我使用几种不同的算法对图片进行降噪处理。 Say I have denoise_1 and denoise_2 and denoise_3. 假设我有denoise_1和denoise_2和denoise_3。 But in the future I will need to add denoise_4, validation_four, etc. 但是将来我将需要添加denoise_4，validation_four等。

I need ALL of the denoise to run on the picture, even the new ones when they get added. 我需要所有降噪才能在图片上运行，即使添加了新的降噪效果也是如此。

In addition : if I add another algorithm I must notify the system. 另外：如果添加其他算法，则必须通知系统。

I am thinking about using strategy and observer patterns, but I have not found an acceptable solution. 我正在考虑使用策略和观察者模式，但没有找到可接受的解决方案。

Is this the right way?? 这是正确的方法吗？

I apologize if for opening a new thread, I found a similar thread but I did not understand the solution. 如果打开新线程，我发现一个类似的线程，但我不了解解决方案，我深感抱歉。

2 个解决方案

Yes strategy is fine: 是的，策略很好：
Let all denoise Algorithm implement a common Interface. 让所有降噪算法实现一个公共接口。

Say all your algorithms implement the same DenoiseAlgorithm . 假设您所有的算法都实现相同的DenoiseAlgorithm 。 Simply place all your algorithms in a List<DenoiseAlgorithm> and run them one by one by iterating over that list. 只需将所有算法放在List<DenoiseAlgorithm>并通过遍历该列表逐一运行它们即可。

If the list is global, adding new algorithm (at the beginning or the end, you decide) has global effect on the whole system. 如果列表是全局的，则添加新算法（由您决定是在开头还是结尾）会对整个系统产生全局影响。

Also consider chain-of-responsibility pattern. 还考虑责任链模式。
