A Background Model Initialization Algorithm for Video Surveillance
Many motion detection and tracking algorithms rely on the process of background subtraction, a technique which detects changes from a model of the background scene. We present a n...

Including Diffuse Multipath Parameters in MIMO Channel Models
Abstract— Recent findings suggest to split the impulse response of the radio channel into discrete paths and the “diffuse multipath” (DMP). This diffuse part can be describe...
