The present disclosure provides an image capture, curation, and editing system that includes a resource-efficient mobile image capture device that continuously captures images. In particular, the present disclosure provides low power frameworks for processing, compressing, and transmitting images at a mobile image capture device. One example low power framework includes a scene analyzer that analyzes a scene depicted by a first image and determines whether to store the first image in a non-volatile memory or to discard the first image from a temporary image buffer without storing the first image in the non-volatile memory.

A secure dispensing unit includes a housing comprising a first end and a second end and a number of storage assemblies. The number of storage assemblies are arranged in parallel with one another within the housing. Each storage assembly includes a number of compartments arranged linearly along an axis of the housing with each of the compartments being configured to store an item. A cover is coupled with the housing and extends between the first end and the second end such that the cover is positioned over the compartments. An actuator is coupled with the cover, the actuator being configured to retract the cover to draw a distal end of the cover from the first end toward the second end to expose a selected number of compartments.

Systems and methods for reducing latency through motion estimation and compensation techniques are disclosed. The systems and methods include a client device that uses transmitted lookup tables from a remote server to match user input to motion vectors, and tag and sum those motion vectors. When a remote server transmits encoded video frames to the client, the client decodes those video frames and applies the summed motion vectors to the decoded frames to estimate motion in those frames. In certain embodiments, the systems and methods generate motion vectors at a server based on predetermined criteria and transmit the generated motion vectors and one or more invalidators to a client, which caches those motion vectors and invalidators. The server instructs the client to receive input from a user, and use that input to match to cached motion vectors or invalidators. Based on that comparison, the client then applies the matched motion vectors or invalidators to effect motion compensation in a graphic interface. In other embodiments, the systems and methods cache repetitive motion vectors at a server, which transmits a previously generated motion vector library to a client. The client stores the motion vector library, and monitors for user input data. The server instructs the client to calculate a motion estimate from the input data and instructs the client to update the stored motion vector library based on the input data, so that the client applies the stored motion vector library to initiate motion in a graphic interface prior to receiving actual motion vector data from the server. In this manner, latency in video data streams is reduced.

The present disclosure provides a video picture playback method, comprising : monitoring a video stream to detect whether an I-Frame picture arrives; and storing the I-Frame picture or compressed I-Frame picture into a memory when the I-Frame picture arrives.
