Illumination-Invariant Image from 4-Channel Images: The Effect of Near-Infrared Data in Shadow Removal

no code implementations4 May 2020 Sorour Mohajerani, Mark S. Drew, Parvaneh Saeedi

Removing the effect of illumination variation in images has been proved to be beneficial in many computer vision applications such as object recognition and semantic segmentation.

Camera Calibration for Daylight Specular-Point Locus

no code implementations12 Dec 2017 Mark S. Drew, Hamid Reza Vaezi Joze, Graham D. Finlayson

First we prove theoretically that any candidate specular points, for an image that is generated by a specific camera and taken under a daylight, must lie on a straight line in log-chromaticity space, for a chromaticity that is generated using a geometric-mean denominator.

Learning to Detect Blue-white Structures in Dermoscopy Images with Weak Supervision

no code implementations30 Jun 2015 Ali Madooei, Mark S. Drew, Hossein Hajimirsadeghi

We propose a novel approach to identify one of the most significant dermoscopic criteria in the diagnosis of Cutaneous Melanoma: the Blue-whitish structure.
