  • Patent number: 6195463
    Abstract: The present invention relates to a storage device by which image data is hierarchically encoded and stored, and to a technique for reducing the size of the device and increasing processing speed. Size reduction and increased processing speed are realized by hierarchically encoding data stored in memory, by computing higher hierarchical data from lower hierarchy data, and by integrating the memory and the memory accessing circuits all on a single semiconductor chip (e.g., CMOS). The chip includes input writing and output reading, read and write address controllers, memory address decoders, read and write buffers, and a memory cell array.

  • Patent number: 6192159
    Abstract: A method for encoding digital information to be transmitted from a first device to a second device, wherein the digital information is mapped according to a map of n rows and m columns which define a plurality of cells (n×m) and wherein each of said cells has a pixel value. The method is useful for compressing bitmapped images to be rendered by the simplest of graphics engines, Thus the method is particularly suited to the transmission of images to a relatively slow client on which the images are to be rendered in real time and on which any complex decompression would be too costly for such rendering. Raw compression ratios are comparable to those obtained with standard run-length encoding, but the number of drawing primitive calls required to render the compressed images directly is substantially less.

  • Patent number: 6192163
    Abstract: A background predicting process is disclosed which determines, for each designated line of input image data, whether or not the pixels of a particular line are the edge portion of a line drawing. The process finds the brightness value for each pixel, excluding the effects of the brightness of the edge portion in the line drawing (step s1). Next, a background prediction modifying process is accomplished which determines whether or not the effects of a line drawing portion other than the edge are included in the brightness value of each pixel in the line being processed. When the effects of a line drawing portion other than the edge are included, the process finds the brightness value of each pixel excluding this effect (step s2). A background modification is then conducted by modifying the brightness so as to achieve a desired brightness value on the basis of the brightness value of each pixel obtained by this background prediction modifying process (step s3).

  • Patent number: 6185337
    Abstract: In an artificial intelligence system for image recognition, a global image of an object is input from a camera or other optical pick-up device, and is processed in a global image processing means, which performs analytical processing on the global image by extracting global characteristics of the input image and evaluating consistency of the extracted global characteristics. Simultaneously, the image data is processed in a local image processing means which undertakes analytical processing on a plurality of local images defining local portions of the image to be recognized. The local image processing means is constructed by plural modules, each further defined by sub-modules, which conduct respective analyses corresponding to local images having characteristics useful in recognizing the global image, wherein each local processor extracts characteristics of an input local image and evaluates consistency of the extracted characteristic with the object to be recognized.

  • Patent number: 6181817
    Abstract: A joint histogram is used for content-based data object comparison. For a data object which can be described by a plurality of features and values, a set of features describing the data object is selected. A joint histogram is a k-dimensional vector, such that each entry in the joint histogram contains the number of data points in the data object that are described by a k-tuple of feature values. The data object is analyzed according to the set of features and the results entered into the joint histogram. The joint histogram distinguishes the data object from other data objects. Joint histogram comparisons may be used to identify the similarity between two or more particular data objects.

  • Patent number: 6181811
    Abstract: A method and apparatus for optimizing biological and cytological specimen screening and diagnosis. A slide review process is recommended for cytological specimen screening to identify abnormal sub-populations for further review and also diagnosis by a human expert. An automated screener processes a cytological specimen. Using a slide score generated by the automated screener, a slide review process using a slide score classification is determined. The recommendation of slide review processes improves overall performance of the screening process as measured by sensitivity to abnormal specimens, and at the same time reduces the work load of a human reviewer. The system also effectively and smoothly integrates the process of initial screening of the specimen with the process of further review of the specimen and final diagnosis of the specimen.

  • Patent number: 6178253
    Abstract: A process for determining the health of crops in a field and treating the crops in accordance with that determination. The process first establishes, in a field in which the health of the crops is to be determined, at least one predetermined reference area of crops having a determined nutrient, e.g. nitrogen, content. Then, georeferenced aerial photographs are taken of at least a portion of the field. From the photographs, the green plane is determined. From the green plane, a relative greenness map of the field based upon the nitrogen reference area is prepared. The greenness map may be transmitted to a farm vehicle on the field and thereafter, the field may be selectively treated in accordance with the nutrient deficiencies detected and recorded on the greenness map.

  • Patent number: 6175649
    Abstract: An image scanning technique of the present invention shortens the time required for reading images of a plurality of originals set on an original tray. The positions of a lens 18 and a line of CCDs 20 are adjusted, so as to enable a scanning range of the line of CCDs 20 in a primary scanning direction to cover a plurality of originals. A first shooting range Z1 of the line of CCDs 20 covers four trimming areas Tr1, Tr2, Tr5, and Tr6. The procedure of the image scanning technique first reads white reference data of a white reference plate in the first shooting range Z1, then scans the four trimming areas Tr1, Tr2, Tr5, and Tr6 while fixing the shooting range to the first shooting range Z1, and carries out shading correction to correct image data obtained by the scan with the white reference data. This structure requires the process of scanning the white reference plate and updating the white reference data only once for correcting the image data of the plurality of originals.
