Astronomical Image Processing and High Angular Resolution Techniques
Astronomical image processing and high angular resolution observation techniques are two fields which contribute towards improving the ability of image sensors to detect faint stars and moving objects, while multiresolution analysis is used to obtain new high-sensitivity and Super-Resolution in Remotely Sensed Images.
ICCUB Contribution
The ICCUB researchers in the field of image reconstruction are focused on exploiting the use of the wavelet transform to improve the ability of image sensors to detect faint stars and moving objects. The effects of the curvelet transform over interferometric images are also being studied. Moreover, differential photometry is being estimated in adaptive optics observations using a wavelet-based maximum likelihood estimator.
[+]
The ICCUB researchers are also working on obtaining super-resolution using additive-substitutive wavelets techniques on remotely sensed images, as well as in obtaining new high-sensitivity, milliarcsecond resolution results from observations of lunar occultations at Very Large Telescope (VLT) of the European Southern Observatory (ESO).
Lines of Research
- Image deconvolution by means of multiresolution analysis (wavelet transform).
- Image fusion by means of multiresolution analysis (wavelet and curvelet transforms).
- Image superresolution by means of multiresolution analysis (wavelet transform).
- Submilliarcsecond resolution of infrared sources by high time resolution lunar occultations technique.
