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.

摘要： Disclosed is a technique for correcting a pixel defect in the capture of two radiological images with parallax therebetween. Radiation beam is directly radiated to a radiation detector 15 in two radiographing directions, without passing through a subject, thereby acquiring two defect detecting radiological images. A pixel defect in each of the two defect detecting radiological images is detected in advance. A pixel position where the pixel defect occurs is stored in advance so as to be associated with each radiographing direction. Then, radiation beam is radiated to the subject from the two radiographing directions to acquire two radiological images for diagnosis. A target pixel which is disposed at the stored pixel position where the pixel defect occurs in each of the two radiological images for diagnosis is corrected.

摘要： To acquire a high-resolution frame from a plurality of frames sampled from a video image, it is necessary to obtain a high-resolution frame with reduced picture quality degradation regardless of motion of a subject included in the frame. Because of this, between a plurality of contiguous frames FrN and FrN+1, there is estimated a correspondent relationship. Based on the correspondent relationship, the frames FrN+1 and FrN are interposed to obtain first and second interpolated frames FrH1 and FrH2. Based on the correspondent relationship, the coordinates of the frame FrN+1 are transformed, and from a correlation value with the frame FrN, there is obtained a weighting coefficient α(x°, y°) that makes the weight of the first interpolated frame FrH1 greater as a correlation becomes greater. With the weighting coefficient, the first and second interpolated frames are weighted and added to acquire a synthesized frame FrG.
