Histogram Equalization technique is one of the basic methods in image contrast enhancement. Using this method, in the case of images with uniform gray levels (with narrow histogram), causes loss of image detail and the natural look of the image. To overcome this problem and to have a better image contrast enhancement, a new two-step method was proposed. In the first step, the image histogram is...

Abstract. To enable the separation of pre- and postdepositional components length distribution (partially annealed) horizontal confined fission tracks, is corrected by deconvolution. Probabilistic least-squares inversion corrects natural track histograms for observational biases, considering variance in data, modelization, prior information. The histogram validated its variance–covariance matri...

Recent results on the reaction pp → K + ¯ K 0 d (1) at T p = 2.645 GeV/c, obtained in the current experiment at ANKE spectrometer [1], are analysed phenomenologically. The purpose of the analysis is to answer the question whether these data give evidence for production of scalar a + 0 meson in the K ¯ K channel. The experimental K + ¯ K 0-mass spectrum from the reaction (1) is shown in Fig.1 (h...

Molecular simulations are very convenient to get insight into the structure and thermal behaviour of small atomic clusters. In this paper, we show how the classical Monte Carlo method can be used to tackle both the global optimization problem of molecular structure and the finite temperature properties. Smarter schemes to compute the caloric curves are also illustrated in the example of the his...

This paper proposes a feature-based multi-sensor fire detector operating on ordinary video and long wave infrared (LWIR) thermal images. The detector automatically extracts hot objects from the thermal images by dynamic background subtraction and histogram-based segmentation. Analogously, moving objects are extracted from the ordinary video by intensity-based dynamic background subtraction. The...

The thermal radiation distribution within and above the canopy is explored. CUPID model is chosen to simulate the canopy component temperatures. TRGM model, based on 3D realistic structure and radiosity solution, is used to simulate the component brightness temperature distribution within canopy and thermal radiation emission directionality distribution TB (θ) above canopy. It is noted that the...

In the study, a real time pedestrian tracking algortithm is presented using thermal infrared imagery. It makes use of the characteristics of pedestrian body regions in infrared images, which is based on a particle filter framework. The method constructs the regions of interest's (ROI) histogram representation in an intensity-distance projection space model, so as to hurdle the disadvantage of i...

Fluorescence microscopy and intensity histogram analysis techniques were used to monitor spatially-resolved albumin adsorption kinetics to model heterogeneous surfaces on sub-μm scales. Several distinct protein subpopulations were resolved, each represented by a normal distribution of adsorption densities on the adsorbent surface. Histogram analyses provided dynamic information of mean adsorpti...
