Abstract
A video analytics based object counting method which can obtain and process video frames from one or more video sources is proposed. By setting a variety of parameters, calculating a reference point, and a mapping table, a sampled referenced image can be constructed to obtain image pixels variation information according to these parameters. With the changed value of multiple sampling line segments and the pre-defined reference object, total object counts can be estimated by analyzing the whole number of the triggered sampling line segments and their directional states.
