1. Structure Detection in Low Intensity X-Ray Images using the Wavelet Transform
... In the context of assessing and characterizing structures in X-ray images, we compare different approaches. The intensity level is often very low and necessitates a special treatment of Poisson statistics. ... Finally, using a set of ROSAT HRI deep pointings, the presence of small-scale structures in the central regions of clusters of galaxies is investigated. ... Hence, WT has been used for clusters and subclusters analysis (Slezak et al. ...

3. The AstroStat Slog spatial statistics
... Posts tagged ?spatial statistics? ... As a part of exploring spatial distribution of particles/objects, not to approximate via Poisson process or Gaussian process (parametric), nor to impose hypotheses such as homogenous, isotropic, or uniform, various nonparametric methods somewhat dragged my attention for data exploration and preliminary analysis. ... I decide to discuss Kalman Filter a while ago for the slog after finding out that this popular methodology is rather underrepresented in astronomy. ...
