摘要： An intruding object detecting method and an intruding object monitoring apparatus for detecting a target object intruding into an image pickup region while reducing the error detection of moving objects other than the target object. A difference in pixel value between an input image signal and each of different image signals in a predetermined number of frames greater than one is calculated for each pixel to thereby obtain differential images in the predetermined number of frames. The differential images in the predetermined number of frames are synthesized in predetermined proportions to thereby generate a synthesized differential image. The synthesized differential image is binarized on the basis of a predetermined threshold value to thereby generate a binarized image. A binarized object in the binarized image is detected as an object intruding into a monitoring visual field.

摘要： A monitoring method and apparatus for detecting an intruding object within a monitoring field of view by applying a subtraction method to an image obtained from an imaging device. A differential image of luminance values between an input image from the imaging device and a reference background image stored in a storage device is generated. The differential image is binarized using a predetermined binarization threshold value and the bianrization threshold value is changed until a noise level of a bianrized image becomes not greater than a predetermined value and based on a binarization threshold value at which the noise level becomes not greater than the predetermined value, an intruding object is detected.

摘要： A method and an apparatus for detecting an object in the image pickup field by template matching and tracking the detected object. An intruding object is detected from an image acquired by an image pickup device which takes the image of an image pickup field. A template image is formed from the detected object and is stored in a storing unit. A template matching is performed between a present input image of the image pickup field and the template image stored in the storing unit to detect the location of that part of the object which has a maximum degree of coincidence with the template image. An edge detection of the object is performed over a predetermined search area in the present input image which area includes the detected part of the object having a maximum degree of coincidence. Based on results of the edge detection, the detected part of the object is corrected and is determined as the present location of the object. A part of the present input image having the corrected location is a new template image with which the template image stored in the storing unit is updated. Instead of a single template image, a plurality of template images may be used for template matching to assure the tracking of the object with even higher accuracy and stability.

摘要： A moving object recognition method for recognizing a specified moving object in an input image signal in distinction from other objects, and a moving object tracking and monitoring apparatus using the method. One or more moving objects in the input image signal are sequentially detected by the subtraction method, the physical quantities of the detected moving objects are sequentially stored in a memory. Based on this physical quantities, one or more loci of the detected moving objects are determined. A group of physical quantities associated with each locus are stored in a memory as correlated information series of a moving object. Based on the information series thus stored, at least one of a plurality of classification methods is applied to each moving object for determining whether the moving object belongs to the specified moving object or other than the specified moving object. Thus, a detected moving object is recognized as to whether it is a specified moving object or not. A plurality of the classification methods include a method based on the continuity of the locus of a detected moving object, a method based on the smoothness of position change of the detected moving object and a method based on the size of the detected moving object.
