A study on automatic methods based on mathematical morphology for Martian dust devil tracks detection
This paper presents three methods for automatic detection of dust devils tracks in images of Mars. The methods are mainly based on Mathematical Morphology and results of their performance are analyzed and compared. A dataset ...
A robust method for microseismic event detection based on automatic phase pickers
(Elsevier Science, 2013-08)
We present a robust method for the automatic detection and picking of microseismic events that consists of two steps. The first step provides accurate single-trace picks using three automatic phase pickers adapted from ...
Improved automatic impact crater detection on Mars based on morphological image processing and template matching
(Taylor & Francis Ltd, 2017-01-01)
Impact craters help scientists to understand the geological history of planetary bodies. The aim of this paper is to improve the existing methodology for impact craters detection in images of planetary surfaces using a new ...
Methodology for automatic selection of passes in surface grinding
The main purpose of this work is the development of computational tools in order to assist the on-line automatic detection of burn in the surface grinding process. Most of the parameters currently employed in the burning ...
Crater detection in multi-ring basins of mercury
This paper presents the automated detection of impact craters on large regions of Mercury. The processing sequence is composed by three main phases: the first consists on creating the image mosaics of the large areas of ...
Fast and automatic microseismic phase-arrival detection and denoising by pattern recognition and reduced-rank filtering
(Society of Exploration Geophysicists, 2015-07)
We have developed a fast method that allowed us to automatically detect and denoise microseismic phase arrivals from 3C multichannel data. The method is a two-step process. First, the detection is carried out by means of ...
