    • Described is a low power surveillance camera system for intruder detection. The system observes a scene with a known camera motion to generate images with various viewing angles. Next, a background learning mode is employed to generate a low rank matrix for the background in the images. Background null space projections are then learned, which provide a foreground detection kernel. A new scene with known viewing angles is then obtained. Based on the foreground detection kernel and the new input image frame, low power foreground detection is performed to detect foreground potential regions of interest (ROIs), such as intruders. To filter out minimal foreground activity, the system identifies contiguous ROIs to generate the foreground ROI. Focus measures are then employed on the ROIs using foveated compressed sensing to generate foveated measurements. Based on the foveated measurements, the foreground is reconstructed for presentation to a user.
    • 描述了一种用于入侵者检测的低功率监控摄像机系统。 该系统观察具有已知摄像机运动的场景以产生具有各种视角的图像。 接下来,使用背景学习模式来生成图像中的背景的低秩矩阵。 然后学习背景零空间投影,其提供前景检测内核。 然后获得具有已知视角的新场景。 基于前景检测核心和新的输入图像帧,执行低功率前景检测,以检测诸如入侵者的感兴趣的前景潜在区域(ROI)。 为了过滤掉最小的前景活动,系统识别连续的ROI以生成前景ROI。 然后,利用移动压缩感测对ROI进行聚焦,以产生移动测量。 基于移动测量,重建前景以呈现给用户。

    • Described is a fencing ornament that is easily installed and removable. A fencing ornament to be secured to a fence structure includes first and second parallel elongate members and a cross member. The fencing ornament comprises a body portion having first, second, third, and fourth side members, and ornamentation within the body portion. Resilient first and second locking members are received in first and second recesses in the third side member adjacent ends thereof. A lug is provided on the fourth side member. Protrusions provided on each of the first and second locking members are moveable by compressing the locking member such that the lug is received in a hole in the cross member and the protrusions are received in a holes in the elongate members.
    • 描述的是一个易于安装和拆卸的围栏装饰。 要固定到围栏结构的围栏装饰件包括第一和第二平行细长构件和横梁。 围栏装饰品包括具有第一,第二,第三和第四侧面构件的主体部分以及主体部分内的装饰。 弹性的第一和第二锁定构件被容纳在邻近其第三侧构件的第一和第二凹部中。 在第四侧构件上设置有凸耳。 设置在每个第一和第二锁定构件上的突起可以通过压缩锁定构件而移动,使得突出部被容纳在横向构件的孔中,并且突起被容纳在细长构件的孔中。
