  • Patent number: 6681061
    Abstract: An image retrieval method and an image retrieval apparatus are disclosed in which it is possible to identify in which image-information recording medium or in which group an image to be retrieved is included. The image retrieval apparatus has a recording controller for recording image information on a disk drive or a hard disk drive. A reduction/expansion controller generates an index picture of a predetermined group of the image information. A retrieval-information storage unit generates index picture IDs, medium IDs, and folder IDs while correlating the above different types of IDs with each other, and stores the IDs together with the index pictures. With this arrangement, a desired item of image information is retrieved by using the index pictures, the index picture IDs, the medium IDs, and the folder IDs. It is thus possible to obtain a target image by sequentially checking the index picture visually.

  • Patent number: 6678426
    Abstract: Lower resolution source data is synthesized to a higher resolution format for subsequent rendering on a lower resolution output device. Synthesis occurs by selecting or generating and using a synthesis template that represents a configuration of a plurality of pixel data in the higher resolution format into which the lower resolution source data is to be synthesized. A working or active pixel is identified from the lower resolution source data, a synthesis template is selected, and then the synthesis template pixel data is substituted for the working pixel for rendering on the output device. The synthesized higher resolution data is rendered in a manner such that dots represented by the synthesized data are formed interstitially relative to scan lines of the given lower raster/resolution capability of the output device. The working pixel is identified in the lower resolution data by recognizing a configuration of a plurality of pixel data adjacent the working pixel.

  • Patent number: 6674925
    Abstract: An object mask and a set of control points defined for a given frame are subjected to morphological processing to remove false edge points and provide a more robust mask for use in tracking the object in a next frame. The morphological processing is performed on a frame by frame basis corresponding to object tracking so that errors added in by the object tracker do not accumulate, and instead are filtered out. Rapidly moving objects which are troublesome for edge-based object trackers are more readily tracked. Also, regions of low contrast or regions locked onto in the background when trying to identify the object are more readily distinguished and eliminated from the object mask.

  • Patent number: 6671424
    Abstract: Methods of caching tile image constituents of image-mosaics enable a substantially smooth real-time display of portions of the image-mosaic in a view during panning, resizing, or zooming of the view. The method includes using a predictive algorithm to identify tile images to be retrieved from a remote store through a local area network, and for sequencing requests for the retrieval of tile images from the remote store. A scheduler calculates time spent in retrieving and servicing each tile image retrieval request and proportionately pauses retrieval of tile images after each request is serviced in order to prevent over utilizing LAN resources. The advantages are that tile images to be displayed are cached in accordance with a priority to facilitate image display while network data transfers are distributed in time.

  • Patent number: 6665449
    Abstract: The present invention is a modified Radon transform. It is similar to the traditional Radon transform for the extraction of line parameters and similar to traditional slant stack for the intensity summation of pixels away from a given pixel, for example ray paths that spans 360 degree at a given grid in the time and offset domain. However, the present invention differs from these methods in that the intensity and direction of a composite intensity for each pixel are maintained separately instead of combined after the transformation. An advantage of this approach is elimination of the work required to extract the line parameters in the transformed domain. The advantage of the modified Radon Transform method is amplified when many lines are present in the imagery or when the lines are just short segments which both occur in actual imagery.

  • Patent number: 6636647
    Abstract: A first original image and a second original image are input to create a merged image. A superimpose area, which an operator designates using an input device, is set as a superimpose area. A portion of the first original image to be superimposed is determined. A superimposing process is executed by blending the first original image with the merged image with a weighted average. The setting of the superimpose area is to determine an &agr; value indicative of the degree of blend (weight) between the first original image and the merged image. The &agr; value of a portion independently present to the side of the second original image with respect to a center line is forced to be zero. The first original image is superimposed onto the merged image using the determined &agr; value.

  • Patent number: 6628844
    Abstract: A high definition radar imaging system receives SAR image data and adaptively processes the image the data to provide a high resolution SAR image. The imaging technique employs an adaptive filter whose tap weights are computed based upon a constrained Maximum Likelihood Method (MLM). The MLM technique chooses the filter tap weights (i.e., a weighting vector &ohgr;) to satisfy several criteria including: 1) they preserve unity gain for a point scatter at the desired location, and 2) they minimize the perceived energy in the output image. The weights &ohgr; are constrained in norm ∥&ohgr;∥≦&bgr;, to reduce the loss of sensitivity to bright scatters. Significantly, the present invention applies an additional constraint on the iterative selection of the weighting vector &ohgr;, such that the weighting vector &ohgr; shall confined to a particular subspace in order to preserve background information in the image.
