摘要： The present invention relates to a retrieval method for searching a first character element string obtained by subjecting a character string to character recognition for a second character element string. The first character element string includes a first character element and the second character element string includes a second character element. A distance relevant to a similarity between the first character element and the second character element is predetermined between the first character element and the second character element. The retrieval method comprises the steps of comparing the distance with a predetermined reference distance, and determining whether the second character element matches the first character element based on a result of the comparison of the distance with the predetermined reference distance.

摘要： The present technology relates to an encoding device and an encoding method, and a decoding device and a decoding method that are capable of reducing the calculation amount of orthogonal transform processing or inverse orthogonal transform processing. A DWT unit (91) performs a DWT of which the calculation amount is smaller than that of a KLT for residual information. KLT units (92-0 to 92-8) perform separable-type KLTs for a low-frequency component of the residual information that is acquired as a result of the DWT using bases of KLTs of the corresponding intra prediction modes. A coefficient acquired as a result of the KLT and a high-frequency component of the residual information that is acquired as a result of the DWT are losslessly encoded. The present technology can be applied to, for example, an image encoding device.

摘要： The present invention relates to an image processing device and method whereby deterioration of effects of filter processing due to local control of filter processing when encoding or decoding can be suppressed. A boundary control flag generating unit 132 of a control information generating unit 112 generates boundary control flags based on system specification information which a system specification managing unit 141 manages. A control unit 171 of an adaptive filter processing unit 113 determines a processing method for filter processing to be performed as to pixels nearby a slice boundary following the value of the boundary control flag. For example, selection is made to perform filter processing straddling slices or to perform filter processing closed at the present slice. The present invention can be applied to an image processing device, for example.

摘要： The present invention relates to an image processing device, an image processing method, and a program that can reduce processing loads and delays while suppressing decreases in inter prediction precision when motion compensation operations with fractional precision are performed in inter predictions. When a pixel of a predicted image in an inter prediction has a fractional pixel position that is not a ½ pixel position in the horizontal direction and the vertical direction in a reference image, a reference image read unit 41 reads predetermined reference pixels including reference pixels aligned in two oblique directions perpendicular to each other. A FIR filter 42 calculates a pixel in a fractional position in the reference image as the pixel of the predicted image, by using the read predetermined reference pixels. The present invention can be applied to encoding devices that perform compression encoding by H.264/AVC, for example.
