    Abstract: Technologies are generally described for automatically optimizing an efficiency of camera placement, numbers, and resolution in multi-camera monitoring and surveillance applications. In some examples, a fraction of a total area may be monitored at a higher resolution than the rest. Employing techniques such as combinatorial state Viterbi technique or combinatorial state trellis technique, a minimum number of cameras that provide the coverage at the needed resolution may be selected. Similarly, a number of points may be covered with at least a predefined number of cameras. For example, a subject of interest may be tracked in a public area, where specific camera(s) may be used to image the subject's face at a higher resolution than the background.

    Abstract translation: 技术通常被描述为在多摄像机监控和监视应用中自动优化摄像机放置，数字和分辨率的效率。 在一些示例中，可以以比其余部分更高的分辨率监视总面积的一部分。 采用诸如组合状态维特比技术或组合状态网格技术的技术，可以选择以所需分辨率提供覆盖的最小数量的相机。 类似地，可以使用至少预定数量的相机来覆盖多个点。 例如，可以在公共区域跟踪感兴趣的主题，其中可以使用特定的相机以比背景更高的分辨率对被摄体的脸部进行成像。
