(meteorobs) Fireball detection software question - for Jupiter impact flashes

[HEADLIGHTS Studio]

There is a massive function extension library for OCTAVE. Its image
processing functions are available at...

http://octave.sourceforge.net/image/overview.html
 
The awesome thing about OCTAVE, is that almost all the stuff developed (.m
and.mex files) for MATLAB will run unaltered in OCTAVE.

WOW Thomas

Based on my experience with detecting movement in Video, I used iSpy. It was
easy to adjust, reliably detects, in real time, (with the free version as
is) meteors in my noisy analog video, and offers an API for making custom
Plugins. Without investigating the API further, and applying speculation
about the problems of detection of flashes on Jupiter through a telescope, I
can guess that what is needed is custom filters. Assuming the optics of the
telescope are good enough, there is going to be image jitter from the
atmosphere. This will cause the generic motion detector of iSpy to trigger
continuously. As you must well know, typically, Astronomy Image processing
Apps stack video images using an alignment algorithm to "Unjitter" the video
into a static picture. 

What is needed for your task is an algorithm that filters the video. Since
atmospheric effects on video of Planets is low frequency frame-to-frame,
compared to the brief events of meteor flashes, the algorithm needed sounds
entirely possible.

OCTAVE just gained the high ground in Free Software for signal processing
with its new GUI. There is a version for Windows. Octave will perform Image
processing of video files; will require a fast machine.

This begs the question; How prepared are you to develop an algorithm for
your needs?

impact flashes

Last year I began a personal observing project with the goal of
telescopically catching impact flashes on Jupiter. The process is to video
Jupiter and then run .avi files through a flash detection program. 
There are two different softwares:  DeTeCt and Jupiter Impact Detection.

Aside from Comet Shoemaker Levy 9 there have been only four serendipitous
impact detections on Jupiter and they were made by amateurs and noted in
real time at the telescope.

There have been no captures yet by anyone using software.

I am wondering if the flash capture software used for earth striking meteors
which triggers on flashes in real time may be better in some way?

Anyone have any thoughts on this?

What would be the optimum Jupiter impact flash capture software or method?

By the way, I do think the softwares mentioned are very fine and it could
just be that bright impactors striking Jupiter are somewhat rare.

Software:

DeTeCt : http://www.astrosurf.com/planetessaf/doc/project_detect.shtml
