Understanding nitrous oxide (N2O) fluxes from agricultural soils in semi-arid regions is required to better understand global terrestrial N2O losses. Nitrous oxide fluxes were measured from three rain-fed, cropped soils in a semi-arid region of south-western Australia on a sub-daily basis from 1995 to 2014 using automated chambers. Western Australia’s grain-belt includes 7 million hectares of a...

Recognizing scene text is a challenging problem, even more so than the recognition of scanned documents. This problem has gained significant attention from the computer vision community in recent years, and several methods based on energy minimization frameworks and deep learning approaches have been proposed. In this work, we focus on the energy minimization framework and propose a model that ...

A study is underway aimed at increasing understanding of the design of pictorial stimuli in perceptual experiments. Since this work centers on pictorial scenes, a variety of such scenes must be selected as stimuli. The experiments planned require scenes that are perceived to have at least five key areas of interest. Further, each of these must be able to be cropped to versions perceived to have...

Recognizing text in natural scene images refers to the problem of identifying words that present on it. Scene text recognition is very difficult due to some reasons such as, images contain very little amount of linguistic context, interpreting versions of letters and digits are required for scene text recognition and also scene text can appear in any orientation. Most of the existing works are ...
