Abstract:
1. A method of detecting a moving object, comprising: (a) a first dividing step of dividing an input image into a plurality of first unit blocks; (b) a second dividing step of dividing a given background image into a plurality of second unit blocks; (c) a moving block extracting step of comparing said first unit blocks with said second unit blocks for every unit block and extracting a number of said first unit blocks, which are different in brightness distribution pattern from the corresponding second unit blocks, as moving blocks; (d) a moving area setting step of setting a moving area that surrounds said moving blocks extracted in said moving block extracting step; and (e) a brightness comparing step of comparing a distribution of brightness values of the input image with a distribution of brightness values of the background image in the moving area, which is set by said moving area setting step, to discriminate whether or not a moving object appears in the input image based on a size of the moving object.
