近年来，云计算在IT行业掀起了新一轮技术革新浪潮。云计算是一种新兴的计算模型，它是并行计算、分布式计算、网格计算的综合发展，以简单、透明服务的形式提供无限制的计算资源。Hadoop实现的开源云平台提供了并行计算模型MapReduce、分布式文件系统HDFS和分布式数据库HBase等。随着数字图像数据量不断增长，单机模式的图像处理已逐渐不能满足用户需求。文中提出了利用Hadoop云平台实现海量图像的并行化处理，设计了基于MapReduce图像处理的类型和格式，实现了图像处理的并行化。
近年來，雲計算在IT行業掀起瞭新一輪技術革新浪潮。雲計算是一種新興的計算模型，它是併行計算、分佈式計算、網格計算的綜閤髮展，以簡單、透明服務的形式提供無限製的計算資源。Hadoop實現的開源雲平檯提供瞭併行計算模型MapReduce、分佈式文件繫統HDFS和分佈式數據庫HBase等。隨著數字圖像數據量不斷增長，單機模式的圖像處理已逐漸不能滿足用戶需求。文中提齣瞭利用Hadoop雲平檯實現海量圖像的併行化處理，設計瞭基于MapReduce圖像處理的類型和格式，實現瞭圖像處理的併行化。

In recent years, cloud computing sets off a new wave of technical innovation in the IT industry. Cloud computing, based on comprehensive development, is an emerging computing model, of parallel computing, distributed computing, and grid computing are could provide unlimited computing resources in the form of simple and transparent service. Hadoop implementing open source cloud platform could provide parallel computing model MapReduce, distributed file system HDFS, and distributed database HBase and so on. With the increase of digital image data volume, image processing in stand-alone mode gradually could not meet the user's needs. A way to implement parallel processing of mass images with Hadoop loud platform is proposed, the types and formats of image processing based on MapReduce are designed, and the parallelization of image processing is realized.
