Human/object tracking when done on an array of frames is an operation of tracking any mobile target object over a span of time with the help of any mobile or immobile camera. It has been a critical issue in the arena of computer vision as it is used in a number of application fields like security, surveillance, human-computer interaction, augmented reality, video communication, and compression, medical imaging, traffic control, video editing, and assistive robotics. This is a highly studied problem and remains to be a complex problem to solve. In object tracking in any given video, the major task is to trace the target object in upcoming video frames. To track the object efficiently a complete knowledge of the target is needed, also the tracking parameters are required and the type of video is being analyzed is to be known. Object tracking is a principal segment of human-computer interaction in a real-time environment, where the computer obtains a finer model of a real-time world.
