Juno perijove 6, May 19, 2017 Options

[Gerald]

Voting for Perijove 06 started yesterday, and it will last for another almost 7 days.

This time, I'm not quite free of bias, since I'm interested in an extension of the polar time-lapse sequence, especially in a coverage of the north and south polar FFRs and the presumed edge of the respective polar haze disks. I think - well, I'm rather certain - that it's possible to infer short-time dynamics of the FFRs, and of the vortices near the edge of the haze disk. Due to the expected good contact to Earth during the PJ-6 pass we have a good chance to obtain overlapping images of these regions.
More in the discussion section on the missionjuno site. Of course, there are other interesting targets, too; see Glenn's and John Rogers' (Philosophia-47) comments.
A full latitude coverage would allow for a pole-to-pole animation.

I am still looking at seamless blending, especially as it really affects the quality of re-timing an animation.

The brute force method is to render buffer frames at either end of a shot which can be merged over time, the more frames the smoother the blend.

[Gerald]

Yes, that's essentially what I've applied to the PJ1 approach sequence (without enhancement), last year.
I hope, that I'll be able to go a step further, soon. But it will be a lot of number crunching...

An attempt to process details from Geralds PJ06_117...

... At various times people have talked about intentionally adding gaussian noise back into the decompanded values...

Here is a test run comparing discrete decompanding

with randomized decompanding.

The randomized decompanding mimics the loss of information during companding by using any of the possible raw data numbers resulting in the companded value with equally distributed probability (discrete uniform distribution).
To my eyes, there is some low-frequency smoothing effect (plus subtle high-frequency noise), but insufficient to fully adjust for the color discontinuity.

PJ06 Approach Movie

Movie starts out "fuzzy" because initially Jupiter is only 44 pixels across. Shadows cast by moons can be seen in several frames towards the end.

Processed with Juno28g pipeline using parameters:
interframeDelay = 0.373;
spiceYawRate = 11.88921302;
rExtrinsic = -0.002;

New attempts on PJ06_123

This one is based on Gerald Eichstadt's processing...


This is made with the output from Brian Swift's pipeline...
