MapReduce：使用MapReduce框架最容易实现哪些图像处理算法

Question

尽管MapReduce可能不是实现图像处理中使用的算法的最佳方法，但出于好奇，如果我作为初学者尝试它们，这将是最简单的实现方法。

Answer 1

Hadoop is really well suited for large amounts of IO. So for example, you could make a job that blurs an image, using the algorithm in the fork/join tutorial.

To do this, you'd create a MapReduce job with the following characteristics:

1. A Custom, non-splitable input format for each image.
2. A Mapper implementation that does the blurring.
3. An Identity Reducer.

Here's a good post that should get you started.
