Abstract: In order to trigger an out of focus alert when the focus level of a video frame meets a focus criteria, a method is performed including the operations of: receiving a video frame, partitioning the video frame into a plurality of blocks, calculating an array of discrete cosign transformation (DCT) coefficients for at least one of the plurality of blocks using a DCT, classifying each of the at least one of the plurality of blocks based on the array of DCT coefficients for that block, calculating a focus level of the video frame from the block classifications, and triggering an out of focus alert if the focus level meets a focus criteria.
Abstract translation: 为了在视频帧的焦点水平满足焦点准则的情况下触发失焦警报，执行包括以下操作的方法：接收视频帧，将视频帧分割成多个块，计算视频帧的阵列 使用DCT对多个块中的至少一个块的离散余弦变换（DCT）系数，基于该块的DCT系数的阵列对多个块中的至少一个块进行分类，计算视频的焦点水平 框架从块分类，并且如果焦点级别满足焦点标准，则触发失焦警报。

Abstract: Embodiments disclosed herein provide systems and methods for performing video recorder failover. In a particular embodiment, a system for handing a failover of a first Network Video Recorder (NVR) is provided. The system includes a second NVR that receives a video stream and temporarily stores an amount of the video stream to the temporary storage, wherein the amount of the video stream stored in the temporary storage at any given time corresponds to a duration of time sufficient to accommodate a failover of the first NVR to the second NVR. In response to a detection of a failure of the first NVR, the second NVR records the video stream to the second long-term storage and transfers at least a portion of the video stream stored in the temporary storage to the second long-term storage.
