Abstract: This disclosure provides systems, methods, and apparatus for analyzing a video are disclosed. An input video signal can be received and a quality metric associated with the input video signal can be determined. A parameter to be used in a first object tracking process can be selected, based in part on the quality metric associated with the input video signal. A background model can be extracted from the input video signal based on an online median estimate of the intensity values of the pixels in the image frames. The online median estimate can be calculated using a quantile function.

Abstract: A coupon packet housing defines a vertically disposed compartment for receiving a stack of substantially vertically aligned, vertically juxtaposed packets. A forwardly and rearwardly movable reciprocable floor plate underlies the compartment and has a flat surfaced, recessed portion extending rearwardly from its front end to define a generally vertically disposed dispensing shoulder which lies adjacent the rear of the compartment when the plate is in rearward position. The lowermost packet is received in the recessed portion, and is separated from the stack and then the recessed portion when the plate is respectively moved forwardly and thence returned rearwardly.
