The Planets


I took multiple sequences of video and then put them side by side to see how they compared.  Sequences 9 and 12
seem the sharpest. The processing in registax was similar for each sequence; some minor color balance and level
adjustments were made to make each sequence's image comparable to the other sequence's images. Images 9 and 12
were given exagerated contrast, 9b and 12b, to see surface detail. Some of the light spots may be real, though
there are differences between 9b and 12b which make me wary of overinterpreting the small features. I guess we'll
see as Mars gets closer. Compared to the earlier images I used a smoother algorithm for enlarging the images so
the background noise level is lower on these images.  I upsized the original images by a factor of two since they
are _small_ on a 640x480 pixel grid.  I switched to a spline interpolation after I realized that the other resizing
algorithm was introducing artifacts.


Composite Image

I did some repetitive processing of the last long sequence of Mars, 1000 frames cut down by first combining the entire sequence then aligning the frames with the combined image to select the best frames, then combining the best frames to get a better image, then repeat the decimation until down to the 200 best frames.  The limb of the planet got "hot" and blown out but the albedo features on the planet started to show some structure.
