ImageJ as an extensible image processing framework

描述（由申请人提供）：成像是现代生物学家可用的最强大的工具之一，定量显微镜和图像分析的最新进展大大加快了我们对基础生物学和生物医学研究中许多复杂和动态过程的理解。虽然商业和闭源软件程序将始终在图像分析中发挥关键作用，但需要开源程序来推动新算法和方法的开发和部署。由美国国立卫生研究院的韦恩拉斯班德维护和开发的公共领域图像分析程序“ImageJ”是生物科学中广泛使用的图像分析工具。由于其易用性，灵活的脚本语言和插件架构，ImageJ发现自己被非程序员，业余程序员和专业程序员有效地使用。然而，任何成功的软件项目，在经过一段时间的持续增长和程序原始意图范围之外的功能添加之后，都会从随后的审查和重构中受益，ImageJ也不例外。这样的审查有助于程序保持对新人的访问，对专家来说足够强大，并与不断发展的社区相关。现有ImageJ社区的迫切需求，以及由于ImageJ的限制而无法加入社区的研究人员的迫切需求，使我们提出了三个最大利益的目标：目标I -改进ImageJ核心架构核心架构的改进对于ImageJ项目的开发和稳定性是必需的，以及与其他软件的互操作性和支持新功能和应用程序的能力。这将涉及（a）将数据模型与用户界面分开，（B）为算法引入扩展框架，以及（c）扩大图像数据模型。目标II -通过将ImageJ与现有开源程序连接来扩展功能为了确保开发朝着最大化互操作性的实际方向进行，我们将改进的ImageJ框架与两个现有的开源生物学应用程序VisBio（多维可视化）和CellProfiler（对象识别和测量）连接。这些将为ImageJ提供改进的功能，并为其他寻求类似地利用ImageJ的软件提供示例。目标III -在保持兼容性的同时发展社区驱动的开发ImageJ拥有强大的用户群，拥有数千个旨在执行各种任务的插件和宏。因此，对ImageJ平台的鲁莽更改可能会破坏现有代码并赶走现有用户。为了促进不断增长的社区的参与、理解和热情，我们建议采用与其他现代成功的开源项目相一致的几个“最佳实践”，这些实践将建立在ImageJ社区驱动开发的坚实基础上。 公共卫生相关性：成像是现代生物学家可用的最强大的工具之一，定量显微镜和图像分析的最新进展大大加速了我们对许多复杂和动态疾病过程的理解。虽然商业和闭源程序将始终在图像分析中发挥关键作用，但需要继续开发ImageJ作为公共领域的成像处理工具，以便为生物和生物医学研究的不同受众开发和部署新算法和方法。

DESCRIPTION (provided by applicant): Imaging is one of the most powerful tools available to the modern biologist and recent advances in quantitative microscopy and image analysis have greatly accelerated our understanding of many complex and dynamic processes in basic biological and biomedical research. While commercial and closed-source software programs will always play a key role in image analysis, open-source programs are needed to advance new algorithm and method development and deployment to a diverse audience. The public domain image analysis program "ImageJ," maintained and developed by Wayne Rasband at the National Institutes of Health, is a widely used tool for image analysis in the biological sciences. Due to its ease of use, flexible scripting language and plug-in architecture, ImageJ has found itself being used effectively by the non-programmer, the amateur programmer, and the professional programmer alike. However, any successful software project, after a period of sustained growth and the addition of functionality outside the scope of the program's original intent, benefits from a subsequent period of scrutiny and refactoring, and ImageJ is no exception. Such review helps the program to remain accessible to newcomers, powerful enough for experts, and relevant to an evolving community. The pressing needs of the existing ImageJ community as well as of researchers who are hindered from joining the community due to limitations in ImageJ lead us to propose three aims of maximal benefit: Aim I - Improve the ImageJ core architecture Improvements in core architecture are required for the development and stability of the ImageJ project, as well as its interoperability with other software and its ability to support new features and applications. This will involve (a) Separating the data model from the user interface, (b) Introducing an extensions framework for algorithms, and (c) Broadening the image data model. Aim II - Expand functionality by interfacing ImageJ with existing open-source programs To ensure that development proceeds in a practical direction that maximizes interoperability, we will interface the improved ImageJ framework with two existing open-source biology applications, VisBio (multidimensional visualization) and CellProfiler (object identification and measurement). These will give ImageJ improved functionality and serve as examples for other software seeking to harness ImageJ similarly. Aim III - Grow community-driven development while maintaining compatibility ImageJ has a strong, established user base, with thousands of plugins and macros designed to perform a wide variety of tasks. Consequently, reckless changes to the ImageJ platform may break existing code and drive away existing users. To foster participation, understanding, and enthusiasm from a growing community, we propose the adoption of several "best practices" in line with other modern, successful open-source projects, which when taken together will build on ImageJ's solid foundation of community-driven development. PUBLIC HEALTH RELEVANCE: Imaging is one of the most powerful tools available to the modern biologist and recent advances in quantitative microscopy and image analysis have greatly accelerated our understanding of many complex and dynamic disease processes. While commercial and closed source programs will always play a key role in image analysis, the continued development of ImageJ as a public domain imaging processing tool is needed for new algorithm and method development and deployment to a diverse audience for biological and biomedical research.
