With quick development of digital images and the availability of imaging tools, massive amounts of images are created. Therefore, efficient management and suitable retrieval, especially by computers, is one of themost challenging fields in image processing. Automatic image annotation (AIA) or refers to attaching words, keywords or comments to an image or to a selected part of it. In this paper,...

Automatic image annotation is a process in which computer systems automatically assign the textual tags related with visual content to a query image. In most cases, inappropriate tags generated by the users as well as the images without any tags among the challenges available in this field have a negative effect on the query's result. In this paper, a new method is presented for automatic image...

あらまし 本論文では、与えられた画像に適切なテキストラベルを自動的に付与する画像認識 (image annotation) と、与えられたテキストラベルから適切な画像を見つけだす画像検索 (image retrievel) とを、統一的な枠組で取り 扱う画像認識検索 (image annotation retrieval) 問題を取り上げる。この問題に対し、我々は、画像とラベルとの関 係性を表現するトピックモデルを半教師的にかつ簡易に獲得できる新しい機械学習手法 SSCDE (Semi-supervised canonical density estimation) を提案する。提案手法は以下の 2つの要素から構成される。(1) 独自に開発した半教師 型正準相関分析 (SemiCCA)により、従来の正準相関分析と同等の計算量で、少数のラベル付画像から得られる画像 とラベルとの共起情報...
