Abstract: A method, system, and computer-readable medium for synchronizing video are described. The system captures video data with a camera, the video data including a first video data segment and a second video data segment. When a network between the camera and a hub is insufficient to allow downstream real-time streaming of the video data, the system stores the first video data segment on a first storage. When the network is sufficient to allow downstream real-time streaming of the video data, the system transfers the second video data segment from the camera to the hub, reads the first video data segment from the first storage, and transfers the first video data segment to the hub. The system stores the video data segments onto a second storage such that a non-real-time playback from the second storage shows the first video data segment and the second video data segment in sequence.

Abstract: A method may include determining a value indicative of an average intensity of blocks in an image. The blocks include a primary and outer blocks. Each of the outer blocks may have three, five, or more than five pixels. The image may describe an external pixel lying between the primary and at least one of the outer blocks. The external pixel may not contribute to the value indicative of the average intensity of any of the blocks. The image may also describe a common internal pixel lying within two of the blocks. The common pixel may contribute to the value indicative of the average intensity of the two of the blocks. The method may include comparing the value indicative of the average intensity of the primary block to the values of the outer blocks, and quantifying a feature represented by the image by generating a characteristic number.
