Can image J create a Pixel value (brightness) chart from a set of images or a video? If so where can we find the instructions to do so?RegardsThomas Dorman

Good evening Thomas,
it would be quite helpful to know what you mean by "Pixel value (brightness) chart". I'm in the field of image processing for about 40 years but have never heard of this. Is it the collection of the (gray)values that actually are present in an image or is it the (gray)value histogram of an image? For the rest of us, please be more specific.

HerbieThank you for your reply. I have a video of the North Korean KMS 3-2 satellite passing through the field of view of my camera. The satellites magnitude is varying as it tumbles.

Good day Thomas,
yes, the video was quite helpful for getting an idea of the issue! And no, I've no experience with astro-images but... My impression is, that there are several non-moving objects that change their intensity over time which makes simple frame to frame subtraction worthless. Consequently the moving object, the satellite, should somehow be tracked. There are ImageJ-plugins that are made for this but I've never used them. However, there may be a simpler approach if the track is more or less known. You could select the track---i.e. make it an (elongated) ROI (region of interest)--and perform frame to frame subtraction restricted to this ROI. If the background is sufficiently stable, this approach isolates the object and it should be rather easy to determine its gray value in every frame. You may just try the approach using a few frames and if it works you may write a little ImageJ-macro to automate the procedure.

Hi Thomas,
two more ideas: (1) Take the average of the stack; this should be only the stars. Then threshold them, create a selection, enlarge it slightly and delete (set to background value). Maybe the satellite is already the brightest object, then the maximum intensity of all slices would be sufficient. You can also set a selection (e.g. polygon) to restrict the measurement to the path of the satellite. (2) Otherwise, write a macro: Get the position in the first and last slice (see the getCursorLoc function) For each slice, get the linear interpolation of the two positions, set a circular selection there and measure the mean or maximum. You can also have two circles (concentric), measure the mean pixel value and area of both and use this for background subtraction to get the desired intensity I: mean1 = I/area1 + background mean2 = I/area2 + background, and thus mean1 - mean2 = I(1/area1 - 1/area2), which finally gives you the intensity without background I = (mean1 - mean2) / (1/area1 - 1/area2) Of course, it won't work if one of the circles contains a background star.

Herbie, Michael, Ben WeiThis may be beyond our capabilities, seems like a very steep learning curve and know zero about programming or writing script. Was looking for a simple straight forward way to get a magnitude variation plots for satellite we video and image so we can get some understanding of tumble and flash rates.We did take some time and played with the plot function but but it hurt our little head trying to wrap our mind around the process. ;O) Thank you all for your kindness,reply's and help it was greatly appreciated.

Herbie, Michael, Ben Wei
Finally after melting our brain we have a working 3D animated surface plot of our video and the KMS 3-2 varying brightness. One issue we have and can not figure out is how to get more tic or line on the vertical intensity or brightness scale. Thanks for taking your time and helping us figure this out. Now we must go and put a ice pack on our aching head. ;O)The short animation can be found here.http://vid284.photobucket.com/albums/ll34/skyflash_14700/KMS%203-2%20tumble%20Surface%20Plot_zpshlqnepi4.mp4RegardsThomas Dorman On Tuesday, March 1, 2016 4:15 AM, Thomas Dorman <[hidden email]> wrote: Herbie, Michael, Ben WeiThis may be beyond our capabilities, seems like a very steep learning curve and know zero about programming or writing script.

Good evening Thomas,
I'm not quite sure whether the pseudo 3D representations will help you much with quantifying the object fluctuations. It remains somehow unclear how you ended up with this movie but I guess you generated it frame by frame. If so, you could adjust the maximum intensity of the frames first to the maximum value of the satellite taken from all frames. Of course the bright stars then will show their intensities clipped. (Don't forget to make the changes permanent by clicking "Apply" in the "Brightness/Contrast"-dialog.) I'm you will need another approach for quantitative analyses ...
