Software for producing trichromatic images in astronomy

چکیده
We present a software package for combining three monochromatic images of an astronomical object into a trichromatic color image. We rst discuss the meaning of \true" colors in astronomical images. We then describe the di erent steps of our method, choosing the relevant dynamic intensity range in each lter, inventorying the di erent colors, optimizing the color map, modifying the balance of colors, and enhancing contrasts at low intensity levels. While the rst steps are automatic, the last two are interactive.

DASTWAR: a tool for completeness estimation in magnitude-size plane
Today, great observatories around the world, devote a substantial amount of observing time to sky surveys. The resulted images are inputs of source finder modules. These modules search for the target objects and provide us with source catalogues. We sought to quantify the ability of detection tools in recovering faint galaxies regularly encountered in deep surveys. Our approach was based on com...
متن کاملExperimental evidence that primate trichromacy is well suited for detecting primate social colour signals
Primate trichromatic colour vision has been hypothesized to be well tuned for detecting variation in facial coloration, which could be due to selection on either signal wavelengths or the sensitivities of the photoreceptors themselves. We provide one of the first empirical tests of this idea by asking whether, when compared with other visual systems, the information obtained through primate tri...

متن کاملSpectral Estimation Using Trichromatic Digital Cameras
In this paper we present an alternative way to capture multi-spectral images using a conventional trichromatic digital camera combined with either absorption filters or multi-illumination. The goal in this research has focused on reducing the cost and complexity of the image acquisition system while preserving its colorimetric and spectral accuracy. This paper describes this new paradigm and su...
