Abstract
A moving object identification method (10) for identifying and tracing an object (20) within a video image (14) such that the object (20) can act as a hot spot (30) as for an interactive computer/user interface (70). A plurality of tags (28) define the edges (26) of the object (20) and a plurality of hot spot borders (32) define the hot spot (30) such that the hot spot (30) and the object (20) generally coincide. A physical tag (28b) is optionally used to position the tags (28). Sensitivity to disappearance of the edges (26) is adjustable according to the relative size of a subtag (68) to the corresponding tag (28).
