Abstract:
1. An image processing apparatus for detecting an input image received from a camera, the camera being adapted to photograph the inside of a monitor area, and monitoring the inside of the monitor area by using an object recognition method, the apparatus comprising: means for inputting set-up information of the camera, and object detection range inside the monitor area, and a real size of an object desired to be detected; means for selecting a point at which the size of the object desired to be detected is minimized inside the object detection range, and for calculating a reduction coefficient from a lump of pixels of the object at the selected point based on the set-up information of the camera, the object detection range inside the monitor area, and the real size of the object desired to be detected; means for storing an image of the monitor area viewed from the camera as a background image; means for storing an actual image viewed from the camera as the input image; means for inputting said input image and said background image and for reducing both of said input image and said background image using said reduction coefficient to prepare a reduced input image and a reduced background image, respectively; means for performing a differential process between said reduced input image and said reduced background image to prepare a difference image, wherein the background image is eliminated from the difference image; means for binary-coding the difference image to prepare a monochrome image composed of a minimum brightness and maximum brightness, based on a predetermined threshold; means for generating a noise eliminated image be eliminating the lump of pixels as a noise region from the monochrome image; wherein the noise region is not included in the number of pixels corresponding to the real size of the object desired to be detected; and means for recognizing the object from said noise eliminated image.
