Semivariogram and Semimadogram functions as descriptors for AMD diagnosis on SD-OCT topographic maps using Support Vector Machine.
Alex Martins Santos,Anselmo Cardoso de Paiva,Adriana P. M. Santos,Steve A. T. Mpinda,Daniel Lima Gomes,Aristófanes Corrêa Silva,Geraldo Braz,João Dallyson Sousa de Almeida,Marcelo Gattas +8 more
TL;DR: The presented methodology exclusively uses geostatistical descriptors for the diagnosis of AMD in SD-OCT images of the macular region and the results are promising and the methodology is competitive considering previous results published in literature.

TL;DR: A methodology to distinguish Mass and Non-Mass tissues on mammograms is proposed, based on the computation of geostatistical measures (Moran's Index and Geary's Coefficient) over a multiresolution image representation trough wavelet transform.

Phytosanitary risks and agronomic performance of soybeans associated with spatial arrangements of plants.
E. L. do Carmo,A. G. da Silva,Geraldo Braz,S. de O. Procópio,Gustavo André Simon,AC Rocha,L. C. Barcellos +6 more
TL;DR: There was a more evident risk of caterpillar incidence in arrangements that promoted better equidistance among plants and the increase in application rate from 75 to 150 L ha promoted superior spray deposition volumes, and increases in grain yield was noted in the narrow arrangement.
