Object detection system and object detection method using codebook algorism

PURPOSE: An object detection system and an object detection method using codebook algorism are provided to discriminate the object from a background by a time threshold value. CONSTITUTION: The object detection system and object detection method using codebook algorism includes a camera, an object detecting means, an object tracking means, a post treatment means and a database. The camera(10) outputs the image pixel by taking a photograph of an image per a frame in real time. The object detection means determines whether the color distortion value is less than the color threshold value by comparing a CW value with an input pixel. The object tracking means labels and gives ID to a circumscribed tetragon which contacts the input pixel. The post treatment means(300) is to make an imperfect circumscribed quadrilateral having the recess portion perfect. The database(500) stores the photographed input pixel and the CW.
