Illumination compensation in ground based hyperspectral imaging
5 Hyperspectral imaging has emerged as an important tool for analysing vegetation data in 6 agricultural applications. Recently, low altitude and ground based hyperspectral imaging so7 lutions have come to the fore, providing very high resolution data for mapping and studying 8 large areas of crops in detail. However, these platforms introduce a unique set of challenges 9 that need to be overco...
متن کاملA Novel Method to Compensate Variety of Illumination in Face Detection
This paper describes a novel method LogAbout to compensate variety of illumination in face detection. The highlight and shadow parts of the image are rendered further away from the transformation we proposed, thus increasing the image contrast. Some traditional methods based on spatial-domain are introduced in this paper. Experiments and Comparisons with each scheme we introduced are presented....
متن کاملApplication of the Hough transform to correct for linear variation of background illumination in images
The Hough t ransform has been formulated to detect areas of linear brightness variation within an image. The formulation leads to significant computat ional advantage involving a restricted parameter search space. Two applications are included to demonstrate the efficacy of this technique.
متن کاملThe Effect of FEW Scatter Correction Method in In-111 Imaging
Introduction: In nuclear medicine imaging, detection of the scattered photons along with the primary photons is one of the major problems that can lead to a decrease in ddiagnostic accuracy. Therefore, use of a suitable scatter correction method can help to improve of the image quality and increase of diagnostic accuracy. The aim of this study is evaluation of five energy wind...
متن کاملENmix: a novel background correction method for Illumina HumanMethylation450 BeadChip
The Illumina HumanMethylation450 BeadChip is increasingly utilized in epigenome-wide association studies, however, this array-based measurement of DNA methylation is subject to measurement variation. Appropriate data preprocessing to remove background noise is important for detecting the small changes that may be associated with disease. We developed a novel background correction method, ENmix,...
