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.

A method of detecting a region having a specific shape in a camera is provided. The method includes processing input image data in a camera and detecting the region having the specific shape. The method includes calculating gradation differences between a central pixel and respective peripheral pixels in each of local regions of an image frame, comparing an average gradation difference with each of the gradation differences and obtaining local gradient pattern (LGP) values based on a comparison result in each of the local regions, and detecting the region having the specific shape from the image frame using the LGP values obtained from the respective local regions.
