    摘要: Image data is separated into two components having elements arranged in a checkered pattern. A dummy setting component is obtained of the signal value occurring at the hole position of the first component, which is dummy-set corresponding to the direction of signal change of the first component. The dummy setting component is subtracted from the second component to obtain a difference component, which is the high-frequency component. By performing weighted addition on the signal value occurring at the hole position of component 1 and the signal value of the difference component, an addition dummy setting is obtained, and is then added to component 2 to obtain the low-frequency component. By repeatedly subjecting the low frequency-component to this processing, the image data can be transformed into the high-frequency components and the low-frequency components of a plurality of frequency bands.

    摘要: The computation of an R06-signal at a G06-pixel position that has only a G-signal on a line of B-pixels and G-pixels is performed by an equation of R06=G06+(R09+G09), based on the assumption that the difference between an R-signal and a G-signal is constant at local regions of an image, i.e., the assumption that a relation of R06−G06=R09−G09 is established. In this case, the G09-signal at the R09-pixel position is computed by performing a one-dimensional interpolation on a G-signal on an RG line including the R09-pixel position, like G09=(G05+G13)/2, etc.

    摘要: An image encoding method includes a step in which image data of components other than image data of components representing the transparency of an image is encoded from among image data of components which includes image data of components representing the transparency of the image, and a step in which an image file is created from image data of components encoded in the encoding step and image data of components other than image data of components encoded in the encoding step. Accordingly, because image data of components representing the transparency of the image is not encoded in the encoded image file, the image shape can be recognized. Moreover, because the image data of the remaining components is encoded, the security of the details of the image data can be maintained.

    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.
