Information content in astronomical images
The performance of optical imaging systems is limited by the signal-to- noise ratios and statistical characteristics of the imaging channel according to O'Neill (1963). In this context, a statistical model for astronomical images is defined and its Shannon information content evaluated in terms...

| description | The performance of optical imaging systems is limited by the signal-to- noise ratios and statistical characteristics of the imaging channel according to O'Neill (1963). In this context, a statistical model for astronomical images is defined and its Shannon information content evaluated in terms of the imaging parameters and the object and noise statistics. (C.E.) |
