... It is sometimes useful, as in image restoration where we want to evaluate the quality of the restoration, to compare images with an objective criterion. ... The correlation between the original image and the restored one gives a classical criterion. ... For each dyadic scale, we can compute the correlation coefficient and the quadratic error between the wavelet transforms of the original and the restored images. ... Figures and show the comparison of three images with a reference image. ...

We present an exhaustive quantitative comparison of all the known extinction curves in the Small and Large Magellanic Clouds (SMC and LMC) with our understanding of the general behavior of Milky Way extinction curves. ... The near-infrared extinction curves are calculated mainly from 2MASS photometry supplemented with DENIS and new JHK photometry. ... This result strengthens the picture dust extinction curves exhibit of a continuum of properties between those found in the Milky Way and the SMC bar. ...

We need simple numbering scheme, so that for any given point we could easily calculate the number of "pixel", this is what HealPix provides and lacks HTM. ... During Rtree queries the number of index blocks read is several times greater than during Q3C queries. ... But in Q3C scheme, as we showed before, the circle is segmented, so we extract from the database only a few percents more data than occur in the circle. ...

... Initial mass function and binary stars . ... The principal goal of this study is to show that the real shape of the initial mass function for low- and intermediate-mass stars differs from the observed one. In particular, comparison of radii of eclipsing binary components and single stars shows a noticeable difference for B0V-G0V components of eclipsing binaries and single stars of the corresponding spectral type. ...
