A method and system for detecting a motion of a target object in a thermal image by removing a shadow by heat of the target object from the thermal image. The motion detecting system includes: a learning unit obtaining at least one of size and brightness of a shadow by heat of a reference object based on characteristics of the shadow by heat of the reference object by temperature; and a detecting unit removing a shadow region of the target object from the thermal image including the target object based on at least one of the size and the brightness of the shadow by heat of the object.

Method and system for detecting motion capable of removing shadow by heat

An image surveillance system and a method of detecting whether an object is left behind or taken away are provided. The image surveillance system includes: a foreground detecting unit which detects a foreground region based on a pixel information difference between a background image and a current input image; a still region detecting unit which detects a candidate still region by clustering foreground pixels of the foreground region, and determines whether the candidate still region is a falsely detected still region or a true still region; and an object detecting unit which determines whether an object is left behind or taken away, based on edge information about the true still region.
