  • Patent number: 6580805
    Abstract: A music score image is read, a two-valuing threshold is set based on a staff interval and a line width of the staff so as to input the music score image as a two-valued image, then music signs are recognized to prepare data for playing and/or music score displaying. With this arrangement, the image two-valuing threshold which seriously affects the recognition rate can be automatically set to an optimum value for the recognition.

  • Patent number: 6580806
    Abstract: An image processing apparatus which can conveniently perform editing processing of image information based on template information and storage and output of the processing result is provided. In the apparatus, the image information used for template information storage is determined based on reference relation information which represents reference relation between the template information and the image information, and the determined image information is stored into an external storage unit together with the template information.

  • Patent number: 6574349
    Abstract: Supplemental data is embedded in an information signal such as a sigma-delta modulated audio signal. The encoded signal includes two or more channels, e.g. a left channel bit stream and a right channel bit stream. The same supplemental data is accommodated at corresponding predetermined bit positions, e.g. every Mth bit position, of the bit streams. This allows detection and extraction of the supplemental data without the need for accommodating a sync pattern in the signal. At the receiving end, a sequence of Mth bits from the first channel is compared with a corresponding sequence of Mth bits from the second channel. If they are identical, the sequence is a candidate supplemental data sequence. This is done for different sequence positions until the supplemental data has been found.

  • Patent number: 6574351
    Abstract: The present invention provides a destination area detection apparatus comprising: destination area candidates generator 21; feature amount extractor 22 for calculating a feature amount of each of the destination area candidates; storage unit 3 for storing a feature amount and a destination probability of the destination area candidate for the feature amount in correlation with an addresser probability which is a probability of an area other than the destination but has an identical configuration as the destination; destination-addresser probability calculator 23 for conversion into a destination probability and addresser probability of each of the destination area candidate by referencing the feature amount in the storage unit 3; sorting unit 24 for deciding the order of the destination area candidates according to the obtained destination probability and the addresser probability; and output candidate decision unit 25 for selecting a predetermined number of destination area candidates having higher destinati

  • Patent number: 6567537
    Abstract: A system and method for assessing plant stress in agricultural crops or crop yields from non-invasive measurements. Aerial digital cameras filtered with two narrow (≦25 nanometers) spectral bandpasses provide digital matrix data representing the absorption spectrum of Chlorophyll &agr; at 680 nm (red) and biomass reflectance at 770 nm (far red). The digital data is corrected and transformed by computer to generate an “Algorithm Image”. The Algorithm Image represents the chlorophyll content for the stand of vegetation, and its interpretation provides information regarding plant stress and is useful in predicting crop yield.

  • Patent number: 6563938
    Abstract: A sheet-through document reader for reading an image formed on a surface of a document original being transported through a reading position. The document reader includes: a reading mechanism for performing main scanning to scan the surface of the document original in a direction perpendicular to a document transport direction at the reading position thereby to read an optical image of the document original, and converting the optical image into image signals; an abnormal value detection circuit for determining whether or not any abnormal value is present in image signals obtained by performing the main scanning by means of the reading mechanism, for example, before the document is read; and a reading position shifting mechanism for shifting the reading position in the document transport direction when the abnormal value detection circuit detects an abnormal value.

  • Patent number: 6560360
    Abstract: A recognition system is disclosed, including a representation of an object in terms of its constituent parts that is translationally invariant, and which provides scale invariant recognition. The system further provides effective recognition of patterns that are partially present in the input signal, or that are partially occluded, and also provides an effective representation for sequences within the input signal. The system utilizes dynamically determined, context based expectations, for identifying individual features/parts of an object to be recognized. The system is computationally efficient, and capable of highly parallel implementation, and further includes a mechanism for improving the preprocessing of individual sections of an input pattern, either by applying one or more preprocessors selected from a set of several preprocessors, or by changing the parameters within a single preprocessor.

  • Patent number: 6553136
    Abstract: A system and a method for preventing counterfeiting activities utilize an image detection scheme that uses only a few portions of restricted-document images, i.e., templates, to determine whether an input image is a duplicate of a restricted-document image. The image detection scheme can reliably operate at very low resolutions, which allows the use of small kernels for image correlation and reduces the number of pixels that have to be actually processed. The system is designed to be incorporated into a host device, such as a copy machine, a scanner, a personal computer or a printer, to detect a potential counterfeiting activity, so that an appropriate action can be taken to prevent and/or to report the detected activity. The image detection scheme allows the system to operate at an increased detection speed, while minimizing the memory requirement.

  • Patent number: 6526154
    Abstract: A method and an apparatus which defines the amount of wood material present in a bark flow and controls a debarking process on the basis of the data to reduce wood losses in the debarking process. In accordance with the invention, the bark flow is imaged by a camera and an image processing unit processes the image by using different whitenesses of the picture elements or pixels of the image as a basis for defining programmatically the amount of wood material in the bark flow. The image processing unit is adapted to produce an output signal for controlling the debarking process. In addition, the invention also provides a method and an apparatus which defines the amount of wood material in a bark flow being moved to a combustion process and controls the combustion process on the basis of the data.
