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.
