Progressive scanning conversion apparatus

Abstract: A progressive scanning conversion apparatus for converting an interlaced scan video signal into a progressive scan video signal by performing interpolation based on original pixels which are obtained in a matrix by sampling the interlaced scan video signal in a current field, original pixels which are obtained in a matrix by sampling the interlaced scan video signal in a previous field which is immediately prior to the current field, and original pixels which are obtained in a matrix by sampling the interlaced scan video signal in a next field which is immediately following the current field The apparatus includes a motion vector detector for detecting a motion vector between two of the current field, the previous field, and the next field; a motion estimation circuit for estimating a pixel value in the current field, from one of a pixel in the previous field and a pixel in the next field using the motion vector detected by the vector detection means; and an interpolated pixel generator for generating an interpolated pixel used for conversion by multiplying the pixel value obtained by the motion estimation means and the corresponding pixel value in the current field by a weighting factor and summating the multiplication results

Nonvolatile memory element, manufacturing method thereof, and nonvolatile semiconductor apparatus using the nonvolatile memory element

Abstract: A nonvolatile memory element comprises a first electrode layer ( 103 ), a second electrode ( 107 ), and a resistance variable layer ( 106 ) which is disposed between the first electrode layer ( 103 ) and the second electrode layer ( 107 ), a resistance value of the resistance variable layer varying reversibly according to electric signals having different polarities which are applied between the electrodes ( 103 ), ( 107 ), wherein the resistance variable layer ( 106 ) has a first region comprising a first oxygen-deficient tantalum oxide having a composition represented by TaOx (0

Dry etching method, fabrication method for semiconductor device, and dry etching apparatus

Abstract: When etching is performed with respect to a silicon-containing material by using a dry etching apparatus having a dual power source, the application of bias power is initiated before oxidization proceeds at a surface of the silicon-containing material. Specifically, the application of the bias power is initiated before the application of source power is initiated. Alternatively, the source power and the bias power are applied such that the effective value of the source power reaches a second predetermined value after the effective value of the bias power reaches a first predetermined value.

Real-time image recording/producing method and apparatus and video library system

Abstract: The real-time image recording/reproducing apparatus of this invention includes: image input means (2) for receiving an image signal; compression means (4) for compressing the image signal so as to produce compressed data; storing means (3) for storing the compressed data; control means (1) for judging whether or not a sufficient empty space required for storing the compressed data exists in the storing means (3), and storing the compressed data in the storing means (3) if a sufficient empty space exists, or allocating a required empty space by releasing oldest data among the compressed data stored in the storing means (3) and storing the compressed data in the allocated empty space if a sufficient empty space does not exist; instruction input means (5) for receiving replay instruction; expansion means (4) for expanding the compressed data stored in the storing means (3) in response to the replay instruction input from the instruction input means (5) so as to produce image data; and output means (6-8) for outputting the image data.

Method and apparatus for named entity recognition in natural language

Abstract: The present invention provides a method for recognizing a named entity included in natural language, comprising the steps of: performing gradual parsing model training with the natural language to obtain a classification model; performing gradual parsing and recognition according to the obtained classification model to obtain information on positions and types of candidate named entities; performing a refusal recognition process for the candidate named entities; and generating a candidate named entity lattice from the refusal-recognition-processed candidate named entities, and searching for a optimal path. The present invention uses a one-class classifier to score or evaluate these results to obtain the most reliable beginning and end borders of the named entities on the basis of the forward and backward parsing and recognizing results obtained only by using the local features.
