  • Patent number: 7602943
    Abstract: An image processing apparatus includes a map generation unit, a temporary area arrangement unit and a target area detection unit. The map generation unit acquires a map of scores in which each score pertaining to a degree—to which a corresponding unit area of image data is likely to be contained in a target area—is associated with a position of the corresponding unit area. The temporary area arrangement unit arranges a temporary area in a position determined in accordance with a predetermined condition, on the map of scores. The target area detection unit performs, at least once, at least one of: (1) processing of changing the position of the temporary area on the map of scores, and (2) processing of changing a ratio of a length of the temporary area in a predetermined direction to that of the temporary area in an orthogonal direction.

  • Patent number: 7227985
    Abstract: A data classifier classifies a plurality of input pattern data into one or more clusters. For each pattern data, a cluster to which the pattern data belongs is provisionally determined. For each cluster, a predetermined correlation value is calculated between one or more pattern data belonging to the cluster and observational pattern data which is a target to be classified into a cluster. A cluster to which the observational pattern data belongs is determined based on the correlation values.

  • Patent number: 7162085
    Abstract: A pattern recognition method and apparatus decrease the amount of computation for pattern recognition and adapts flexibly to an increase and a change in learning samples. Learning is made beforehand on base vectors in a subspace of each category and a kernel function. Pattern data to be recognized is input, and projection of an input pattern to a nonlinear subspace of each category is decided. Based on the decided projection, a Euclidean distance or an evaluation value related to each category is calculated from the property of the kernel function, and is compared with a threshold value. If a category for which the evaluation value is below the threshold value exists, a category for which the evaluation value is the smallest is output as a recognition result. If there is no category for which the evaluation value is below the threshold value, a teaching signal is input for additional learning.

  • Patent number: 6654730
    Abstract: When neuron operations are computed in parallel using a large number of arithmetic units, arithmetic units for neuron operations and arithmetic units for error signal operations need not be provided separately, and a neural network arithmetic apparatus that consumes the bus band less is provided for updating of synapse connection weights. Operation results of arithmetic units and setting information of a master node are exchanged between them through a local bus. During neuron operations, partial sums of neuron output values from the arithmetic units are accumulated by the master node to generate and output a neuron output value, and an arithmetic unit to which neuron operations of the specific neuron are assigned receives and stores the neuron output value outputted from the master node.
