Although fertility capability classification (FCC) has high performance in land evaluation and soil maps interpretation, so far it has been less attended in land evaluation studies. Therefore, qualitative (FCC method) and quantitative (Riquer index) land fertility capability evaluation for Wheat and Rice cultivation and comparison of Soil Taxonomy and WRB classification with FCC were chosen as ...

BACKGROUND Traditional sources of species occurrence data such as peer-reviewed journal articles and museum-curated collections are included in species databases after rigorous review by species experts and evaluators. The distribution maps created in this process are an important component of species survival evaluations, and are used to adapt, extend and sometimes contract polygons used in th...

This paper aims at describing a new framework which allows for the quantitative combination of different edge detectors based on the correspondence between the outcomes of a pre-selected set of operators. This is inspired from the problem that despite the enormous amount of literature on edge detection techniques, there is no single one that performs well in every possible image context. The so...

Blur is a key factor in the perception of image quality, leading to spread of edges in images. The quantity of feature points extracted from images can represent image shape changes. Compared with sharp images, blurred images tend to contain less feature points, and the reduction of feature points is related to blur. In this paper, we propose a new blind blur assessment metric based on feature ...

Since data in OpenStreetMap is mostly surveyed by untrained private citizens rigorous quality control is required in order to produce a reliable data set. “Hidden” information, such as user activities, topicality of data, which is typically not visualized in maps might indicate areas with increased need for quality assessments. OSMatrix is a visual analytics approach that provides such informat...
