Proceedings ArticleDOI
Illumination-invariant color object recognition via compressed chromaticity histograms of color-channel-normalized images
Mark S. Drew,Jie Wei,Ze-Nian Li +2 more
TL;DR: The seminal method of Swain and Ballard to discount changing illumination is extended, based on the first stage of the simplest color indexing method, which uses angular invariants between color image and edge image channels.
Journal ArticleDOI
Illumination–invariant image retrieval and video segmentation
Mark S. Drew,Jie Wei,Ze-Nian Li +2 more
TL;DR: It is shown that the color constancy step – color band normalization – can be carried out in the compressed domain for images that are stored in compressed form, and that only a small amount of image information need be decompressed in order to calculate the new metric.
Journal ArticleDOI
Markov edit distance
TL;DR: Inspired by the success of the Markov Random Field theory, a new edit distance called Markov edit distance (MED) within the dynamic programming framework is proposed to take full advantage of the local statistical dependencies in the pattern in order to arrive at enhanced matching performance.
Journal ArticleDOI
On illumination invariance in color object recognition
Mark S. Drew,Jie Wei,Ze-Nian Li +2 more
TL;DR: This work investigates under what general conditions illumination change can be described using a simple linear transform among RGB channels, for a multi-colored object, and adduce a different underlying principle than that usually suggested.
Journal ArticleDOI
Direct Comparison of Respiration-Correlated Four-Dimensional Magnetic Resonance Imaging Reconstructed Using Concurrent Internal Navigator and External Bellows.
Guang Li,Jie Wei,Devin Olek,Mo Kadbi,Neelam Tyagi,Kristen L. Zakian,James Mechalakos,Joseph O. Deasy,Margie Hunt +8 more
TL;DR: The navigator-triggered 4DMRI scanning protocol should be preferred to the bellows-based, especially for coronal scans, for clinical respiratory motion simulation.
