of feature transformation processing which transforms features of colorectal endoscopic images to Visual Word (VW) histogram. This processing is used in our eCAD system for colorectal endoscopic images with narrow band imaging (NBI) magnification, which is used to identify pathology types from local feature in the NBI endoscopic image. We propose a high speed and low cost feature transformation for CAD system by using Manhattan distance calculation and on-the-fly normalization method. The proposed high speed feature transformation can complete the transformation in real time (60 msec) for Full HD NBI endoscopic image, which has about 83,000 key-points of 64-dimention vector.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"82","bibliographic_titles":[{"bibliographic_title":"DAシンポジウム2015論文集"}],"bibliographicPageStart":"77","bibliographicIssueDates":{"bibliographicIssueDate":"2015-08-19","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"2015"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":144808,"updated":"2025-01-20T18:39:59.297194+00:00","links":{},"created":"2025-01-19T00:20:32.684436+00:00"}
