A Constrained Band Selection Method Based on Information Measures for Spectral Image Color Visualization

2011

International audience; We present a new method for the visualization of spectral images, based on a selection of three relevant spectral channels to build a Red-Green-Blue composite. Band selection is achieved by means of information measures at the first, second and third orders. Irrelevant channels are preliminarily removed by means of a center-surround entropy comparison. A visualization-oriented spectrum segmentation based on the use of color matching functions allows for computational ease and adjustment of the natural rendering. Results from the proposed method are presented and objectively compared to four other dimensionality reduction techniques in terms of naturalness and informa…

Matching heterogeneous job seekers and vacancies : empirical studies using Finnish data

Labor market matching with application to Finnish data

2014

This thesis studies labor market matching and takes use of a matching function, which describes the technology how unemployed job seekers and vacant jobs search, meet and form new employment relationships. The goal of the study is twofold: First is to provide a comprehensive critical review of previous literature covering both micro models as well as empirical applications. Major limitations in empirical studies are imperfect measures of variables as well as inability to account for all relevant factors making results methodology-sensitive. The second contribution is to estimate a matching function for Finland using annual data from 2006-2012 and thus giving the most recent knowledge on the…
