Image Measurements Davi Geiger

It makes no sense to extract features at pixel level as the image is noisy and the discretization/quantization introduces artifacts. The minimum resolution in which we can look an image is an order of magnitude higher than a pixel, i.e., it is a few pixels, say 10 pixels. In an image there are various intensity discontinuities, and these are important information to preserve. Thus, when we are ...

GEIGER: investigating evolutionary radiations

SUMMARY GEIGER is a new software package, written in the R language, to describe evolutionary radiations. GEIGER can carry out simulations, parameter estimation and statistical hypothesis testing. Additionally, GEIGER's simulation algorithms can be used to analyze the statistical power of comparative approaches. AVAILABILITY This open source software is written entirely in the R language and ...

A Magnetically Enhanced Wireless Micro-geiger Counter

This paper reports a micromachined Geiger counter with integrated permanent magnets that enhance the RF transmission from the discharges initiated by incident beta particles. With the intent of wireless sensing within the ultra wideband (UWB) spectrum, the transmission in the 2.0-2.8 GHz frequency range is investigated. The device consists of a 1x2 cm micromachined glass/Si cavity sandwiched be...
