代码说明:

检索图像颜色相似性的基础上的几种方法在文献中,介绍了但最基本思想是相同的变化。添加到集合中的每个图像分析来计算颜色直方图的显示像素为单位) 的每一种颜色在图像内的比例。每个图像的颜色直方图然后存储在数据库中。在搜索时,用户可以指定所需的每一种颜色 (75%橄榄绿色和红色的例如 25%),比例或提交示例图像颜色直方图计算的。无论哪种方式,匹配过程,然后检索这些图像的颜色直方图匹配查询的那些最为密切。Swain 和巴拉 [1991] 第一次提出匹配技术最常用,直方图相交。这种技术的变种现在用于高比例的当前图像检索系统。Swain 及巴拉德的原始技术提高的方法包括使用的累积颜色直方图 [史翠克和奥伦戈,1995年],结合一些元素的空间匹配 [史翠克和 Dimai,1996年),并用查询 [Carsonet al,1997年] 的基于区域的颜色直方图相交。从这些系统的一些结果看起来相当令人印象深刻。

    temperature data logger-The temperature data logger is a device to read temperature and store persistent temperature and corresponding timestamp data into Flash memory. The collection of temperature data can be retrieved, and analyzed after being logged. The temperature data logger is commonly used for monitoring environmental data and shipments of temperature sensitive products such as foods, pharmaceuticals, and some chemicals. In particular, temperature data logger can operate as a stand-alone device and put in a variety of locations including office, laboratory or geographical location such as mountains, deserts,… and in manufacturing line in industry to collect temperature data over a defined period of time. It is also small enough and portable to be integrated with shipping container or directly attached to products which can be degraded due to exposure to temperature extremes to monitor their temperature
