Abstract
A method of detecting a cart-based loss incident in a retail store includes decoding one or more video frames of a video stream to obtain one or more motion vectors therefrom, detecting motion of a shopping cart within a cash register lane bounded by pre-defined tracking start and end points based on the one or more motion vectors, tracking a location of the shopping cart till the shopping cart reaches the pre-defined tracking end point, dynamically classifying the shopping cart in one of a plurality of classification statuses based on recognition of one or more items present in the shopping cart till the shopping cart reaches the pre-defined tracking end point, and generating an alert signal when the shopping cart is classified in a pre-defined classification status from the plurality of classification statuses at an alert threshold point between the pre-defined tracking start and end points.
