Coupling high-resolution satellite imagery with ALS-based canopy height model and digital elevation model in object-based boreal forest habitat type …

2014

We developed a classification workflow for boreal forest habitat type mapping. In object-based image analysis framework, Fractal Net Evolution Approach segmentation was combined with random forest classification. High-resolution WorldView-2 imagery was coupled with ALS based canopy height model and digital terrain model. We calculated several features (e.g. spectral, textural and topographic) per image object from the used datasets. We tested different feature set alternatives; a classification accuracy of 78.0 % was obtained when all features were used. The highest classification accuracy (79.1 %) was obtained when the amount of features was reduced from the initial 328 to the 100 most imp…

The Semantics of Musical Topoi : An Empirical Approach

2015

THE ARTICLE INTRODUCES AN EMPIRICAL APPROACH to studying music’s extrinsic meanings, based on the idea of musical topos as a set of musical entities that is delimited and furnished with meaning by extramusical associations in a listener population. The proposed methodology involves free, associative responses as well as responses on semantic variables addressing the imagery. After deriving potential topical structures for a given musical domain from the quantitative results, the structures are substantiated by using them to guide a rule-based, qualitative analysis of the free responses. The approach allows a view to the topical organization of a musical domain in which the identity of each …

Oppressive Faces of Whiteness in Walter Mosley’s "Devil in a Blue Dress"

2018

Walter Mosley’s Devil in a Blue Dress contributes significantly to the literary debate on the definition of whiteness. The socio-historical construction of whiteness emerging from the novel is amplified by white imagery dovetailing with the claims made about white people directly. For the African American first person narrator, Easy Rawlins, living in post-World War II Los Angeles, whiteness mostly spells terror. The oppressive faces of whiteness consist in the following trajectories: property relations, economic exploitation, labour relations, the legal system, different miens of oppressive white masculinity denigrating blackness, spatial dynamics of post-World War II Los Angeles and the w…
