    • Techniques are described for detecting anomalous events using a long-term memory in a video analysis system. The long-term memory may be used to store and retrieve information learned while a video analysis system observes a stream of video frames depicting a given scene. Further, the long-term memory may be configured to detect the occurrence of anomalous events, relative to observations of other events that have occurred in the scene over time. A distance measure may used to determine a distance between an active percept (encoding an observed event depicted in the stream of video frames) and a retrieved percept (encoding a memory of previously observed events in the long-term memory). If the distance exceeds a specified threshold, the long-term memory may publish the occurrence of an anomalous event for review by users of the system.
    • 描述了在视频分析系统中使用长期记忆来检测异常事件的技术。 长期记忆可用于存储和检索在视频分析系统观察描绘给定场景的视频帧流时所学习的信息。 此外,长期记忆可以被配置为相对于随着时间的过去在场景中发生的其他事件的观察结果来检测异常事件的发生。 距离度量可用于确定活动感知(对视频帧流中描绘的观察事件进行编码)与检索到的感知(对长期存储器中先前观察到的事件的存储进行编码)之间的距离。 如果距离超过指定阈值,则长期记忆可能会公布异常事件的发生,供系统用户查看。

    • An integrated illumination apparatus includes a light injection portion having a first end for receiving light from a light source. The light injection portion includes material that supports propagation of said light along the length of the light injection portion. Turning microstructure is disposed on a first side of the light injection. The turning microstructure is configured to turn at least a substantial portion of light incident on the first side and to direct the portion of the light out a second opposite side of the light injection portion. A slit is disposed along the length of the light injection portion. The slit forms an optical interface on the second opposite side of the light injection portion that provides total internal reflection for light propagating along the length of the light injection portion to be guided therein. The optical interface further transmits light turned by said turning microstructure. A light distribution portion is disposed with respect to the slit to receive the light turned by said turning microstructure and transmitted out of the second side of the light injection portion and through said slit. At least one bridge is disposed between light injection portion and the light distribution portion. The bridge mechanically connects the light injection portion to the light distribution portion.
    • 集成照明装置包括具有用于接收来自光源的光的第一端的光注入部。 光注入部分包括支持沿着光注入部分的长度传播所述光的材料。 转向微结构设置在光注入的第一侧上。 转向微结构被配置成使入射在第一侧上的至少大部分光转向并将光的一部分引导出光注入部分的第二相对侧。 沿着光注入部分的长度设置狭缝。 狭缝在光注入部分的第二相对侧上形成光学界面,该光学界面为沿着光注入部分的长度传播的光提供全内反射,以在其中被引导。 光学接口还透射由所述转动微结构转动的光。 光分配部分相对于狭缝设置以接收由所述转动微结构转动的光并且透射出光注入部分的第二侧并穿过所述狭缝。 在光注入部分和光分布部分之间设置至少一个桥。 桥将光注入部分机械地连接到配光部分。
