At last, the edges of ROIs are detected by using morphological grads.

最后利用形态梯度的算法探测出感兴趣区域的边缘。

Detecting regions of interest(ROIs) is the base step for object's feature extraction, identification and tracking.

感兴趣区域定位是提取目标特征，进行目标识别与跟踪等后续处理的重要基础。

Absrtact: a new ROIs extract method based on mathematical morphology toward applications on remote sense image is presented.

摘要：提出了一种基于数学形态学的遥感图像多感兴趣区域提取算法。

This afternoon, our French chorus came to the Novotel hotel to celebrate the Galette des Rois with French friends who stay in Beijing.

今天下午，我们法语合唱团在诺福特酒店和在京的法国朋友们一起欢度国王饼节。

To calculate ROIs, given the two orchestrators and repositories are in place, consider a theater of three human-facing Web services. They are.

要计算roi，假定两个协调器和相应存储库已就位，还要考虑以下三种面对人的Web服务。

While these figures still correlate with initiatives from which hoteliers believe they will achieve the greatest ROIs, there were some surprises this year.

虽然这些数字与酒店业者认为可从中获得最大ROI的营销方案相吻合，今年还是出现一些意料之外的情况。

Hold off on advertising where you cannot measure results (e.g. print) and ROAS (Return on AD spend), or those that have not resulted in good ROIs in the past.

暂停那些不可测量效果和广告开支回报值(ROAS)的广告(如印刷品)，或者那些ROI较低的渠道。

You will see examples of how you can calculate ROIs to determine the cost effectiveness of a countermeasure or even the implementation of a Web service in the SOAs.

在文中提供了几个示例，以说明如何计算roi来确定对策(甚至SOA中的Web服务实现)的成本效益。

Whatever the countermeasures you choose to increase the ROIs, it is important to integrate the countermeasures in all phases of a Web service development life cycle.

无论选择何种对策来增加roi，都务必将对策与Web服务开发生命周期的所有阶段集成。

Concerning about the disadvantage of formerly provided each method all aimed at coding a Region of interest, a new approach was proposed to realize multiple ROIs coding.

针对以往提供的各种方法都对一个感兴趣区域进行编码的缺点，提出了实现多个感兴趣区域的无损压缩的方法。

For example, many hoteliers are struggling to justify returns from social and mobile marketing initiatives which rarely produce significant ROIs as stand-alone marketing formats.

例如，很多酒店管理者都会执着于社会媒体和手机营销能为他们带来多少回报。如果你只是单独使用这两种营销手段，它们的ROI都不是十分显著。

Likewise, the same ROIs were located on the resting state cerebral cortex and the functional connection mode and distributing of visual system in the resting state cerebral cortex were obtained.

结果发现，不同脑活动状态下，人脑脑区的连接网络是变化的，这种可塑性对人脑完成不同的功能具有非常重要的意义。

In addition to hoteliers believing that social media will produce greater ROIs, the survey also showed a surge in the types of social media that hoteliers are participating in (or planning for 2010).

调研结果显示酒店业者相信社区媒体可带来更高的ROI，同时还反映出酒店业者正在参与（或者计划在2010年参与）的社区媒体种类数量出现猛增。
