Abstract: This paper designs and implements a digital image experiment platform for heterogeneous resource integration, which can be used for solving problem of language diversification and cross-language calls in digital image processing experiment. In order to provide callable and extensible algorithmic components for any client that accesses the Internet, this platform has integrated a variety of common digital image processing algorithms written in different languages. Besides, it provides Web services for components’ centralizing management and calling feedback. Users can choose components implemented by different languages to build experiment flow and further understand algorithms through observing the result. This virtual laboratory platform can meet the needs of university digital image curriculum for its beautiful interface design, good interactivity, excellent system performance and cross-platform support.

Key words: digital image processing, experiment platform, multi-language call, multi-threaded concurrent

摘要： 针对数字图像处理实验中算法实现语言多样化、跨语言调用难等问题，设计并实现了一个面向异构资源集成的数字图像实验平台。平台预先集成了数字图像处理各种常见的由不同语言编写的算法组件，为接入互联网的任意客户端提供了透明高效、可调用和可扩展的算法组件，同时提供了定制实验流程并能对实验进行集中管理和反馈的Web服务。该虚拟实验室平台界面美观，交互性好，使用简单高效，系统性能优异，跨平台支持，能很好满足高校数字图像课程需求。
