The task of visual concept detection, annotation, and retrieval using Flickr photos at ImageCLEF 2012 was organized as two subtasks: concept annotation and concept retrieval. In this paper, we present the effort of KIDS lab for the two subtasks. The proposed approaches combine various visual and tex-tual features, dimension reduction methods, the random(More)
Keap1 is an adaptor protein that regulates Nrf2 in response to oxidative stress. Under basal conditions, Nrf2 is negatively regulated through ubiquitination by Keap1. However, upon exposure to oxidative stress, the ubiquitination of Nrf2 is inhibited, resulting in an increased steady-state level of Nrf2 in the nucleus and increased transcription of(More)
The personal photo retrieval task at ImageCLEF 2012 is a pilot task for testing QBE-based retrieval scenarios in the scope of personal information retrieval. This pilot task is organized as two subtasks: the visual concepts retrieval and the events retrieval. In this paper, we develop a framework of combining different visual features, EXIF data and(More)
