A locally-adaptive approach for image gamma correction

10th International Conference on Information Science, Signal Processing and their Applications (ISSPA 2010), 2010
This paper proposes a new adaptive gamma correction method. The method estimates gamma values in different regions of an image and transforms individual pixels of the image following estimated gamma values. In this method we initially made a database of two feature vectors: pixel intensity histograms and dispersion vs. location distributions, from nine

Gamma-gamma density measurements: basic response and environmental corrections

IEEE Transactions on Nuclear Science, 1989
The basic response of a gamma-gamma density logging tool and the environmental corrections to that response have been determined. This has been accomplished through the use of test formation data and Monte Carlo modeling. The basic response has been determined for formation densities of 1.6 g/cm/sup 3/ to 3.1 g/cm/sup 3/. Environmental corrections have

Correction for decay during counting in gamma spectrometry

Radiation Protection Dosimetry, 2012
A basic result in gamma spectrometry is the count rate of a relevant peak. Correction for decay during counting and expressing the count rate at the beginning of the measurement can be done by a multiplicative factor that is derived from integrating the count rate over time.
