One of the major challenges is to process images in real time using onboard camera on a moving unmanned aerial vehicles (UAV).In this paper we will present a survey of existing methods for detecting and tracking moving objects, using unmanned aerial vehicles. Generally, in literature the proposed methods are based on two parts, motion estimation and object detection and tracking.
