Researcher

Hirobumi Nishida

Hirobumi Nishida is a researcher in structural pattern recognition whose work links character recognition with shape and image retrieval. In 1991, he filed a Ricoh patent for classifying character line patterns, and in 1995 he served as an associate professor at the University of Aizu and chair of IAPR Technical Committee 8 while helping develop a fast Ricoh OCR package. He published a structural model of curve deformation in 1996 and a paper on partly visible shape retrieval in 2000. IAPR named him a Fellow in 2000 for contributions to structural pattern recognition and service; his 2002 Pattern Recognition paper examined structural feature indexing for partially visible shapes. In 2007, he organized an SICE session on image-based measurement as a Ricoh representative, and a Ricoh patent application he filed in 2009 for predicting optimal processing was granted in 2012.

Timeline

  1. 1991–1994

    A character-line patent

    In 1991, he files a Ricoh patent application for classifying character line patterns in a dictionary; it is granted in 1994.

  2. 1995

    Associate professor and IAPR chair

    In 1995, he is an associate professor in the University of Aizu's Image Processing Laboratory and chair of IAPR Technical Committee 8 on Application in Industry. His earlier work at Ricoh's Research and Development Center helps an OCR group develop a fast package called “filtering in character recognition.”

  3. 1996

    Modeling curve deformation

    In 1996, he publishes “A Structural Model of Curve Deformation by Discontinuous Transformations” in CVGIP: Graphical Model and Image Processing.

  4. 2000

    Partly visible shape retrieval

    In 2000, he publishes “Retrieval of Partially Visible Shapes through Structural Feature Indexing” in the joint proceedings of IAPR's SSPR and SPR workshops.

  5. 2000

    An IAPR fellowship

    IAPR names him a Fellow in 2000 for contributions to structural pattern recognition and service to the association.

  6. 2002

    Structural feature indexing

    In 2002, he publishes “Structural feature indexing for retrieval of partially visible shapes” in Pattern Recognition, pages 55–67.

  7. 2007

    Image-based measurement session

    At SICE's 2007 Annual Conference, he co-organizes an Advanced Image-Based Measurement session under the Technical Committee on Pattern Measurement, with Ricoh Co., Ltd. as his affiliation. The session covers noncontact, nondestructive extraction of three-dimensional or spatial information from images.

  8. 2009–2012

    Predicting optimal data processing

    In 2009, he files a Ricoh patent for predicting optimal processing from input features and a user's processing history; the patent is granted in 2012.

  2. The United States employs an estimated 53% of people in our data with a known employment countryOur estimates of where AI careers are concentrated now and how countries’ shares of dated positions changed over time.
  3. 46% of living people in our data with known birth and employment countries work outside their birth countryOur estimate of cross-border careers in AI, from country of birth and the country of each current organization.
  4. More people shaping AI studied at Massachusetts Institute of Technology than at any other institutionOur estimates of where the people shaping AI studied and where their careers led, from education records in cited biographies.
