The proposed method interpolates the sampled R and B channels into high resolution channels through a guided filter that uses the interpolated W channel as a guided value.
In order to overcome the drawback of this CFA pattern, we propose a color interpolation method that reconstructs the four high resolution channels (long exposed W, short exposed W, R, and B) from the sampled low resolution channels.
During the functional testing, the wide-field channel passed, but issues were seen with the high-resolution channel, indicating that the power issue may be farther upstream in the electronic circuits than the spacewalk repair addressed.
Managers and engineers had noted that the repairs were designed for only one of the three photo channels, the wide-field channel, and that the issues with the high-resolution channel may not be resolved by the designed fix.
Even if the high-resolution channel is unable to be restored, it was considered to be less important, since the bulk of the ACS science output is undertaken by the wide-field channel.
Additional testing would be performed, but Hubble Program Manager Preston Burch noted that the fix was designed to "back power" the high-resolution channel through the paths connected to the wide-field channel, and while feasible, it was a possibility that the short circuit damage was in an area not corrected with the planned repair.
In the era of hyperspectral sounders with thousands of high-resolution channels, the computation of the radiative transfer model becomes more time-consuming.
Sedimentological and chemical analysis of gravity core samples, along with the interpretation of very high resolution, single channel seismic reflection profiles acquired off the Sarno prodelta system (southeastern Naples Bay), document the sedimentary facies and seismic stratigraphic signature of the tephra deposit erupted by Vesuvius during the plinian eruption of 79 AD.
In the proposed algorithm, two sampled W channels captured with different exposure times are reconstructed as high resolution W channels using directional color difference information, and the sampled R and B are interpolated using a guided filter.
