Abstract: An important requirement of growing research in machine/computer vision is a reliable and efficient target tracking methods. This letter is a review of selected estimation and tracking algorithms as applied to image processing, these are grouped into two namely: Deterministic based and Nondeterministic based algorithms. Various issues affecting success and/or failure of such algorithms are discussed and presented together with current useful references on the topic. With only two groups of tracking and estimation algorithms, this work is anticipated to guide tracking systems designers in deciding on a suitable algorithm for use. There is no single ideal algorithm for all tracking problems.
