Matlab vs PixInsight

[Epic (Norbert)]

Hi,

I wonder if there are users out there who use Matlab codes to stack and integrate images. I wonder which way I should go: PixInsight or Matlab. I guess it will be faster with PixInsight, but much more fun in Matlab.


I have worked on x-ray CCD data 20 years ago in IDL, so Matlab would be pretty close to it.

Would be nice to access some codes and not having to program everything.

Thanks

I have dabbled in Matlab but find I don't have the patience to go very far with it these days. You would certainly have much greater control over exactly what you were doing to your image but you would need to have an understanding of the functions. If you really grasp what functions like the fourier transforms and convolution do then it would be a great image manipulation tool. Linked to that would be a need to write code to step from one function to the next.

Pixinsight has all of that clad in a more user friendly shell.

Thanks Ulrich!

Appreciate your comments. I am just beginning in astrophotography, so will probably have a go at both...

I use matlab at work a lot, and for fast evaluation of crazy ideas in signal processing and just about any other computational problem it's hard to beat. However, I'd honestly recommend pixinsight for ap instead as it is dedicated to it.
If you want to start trying out some new decon or noise reduction ideas it's easy enough to bring an image into matlab, but I guarantee you'll get better results if you take it back into Pixinsight afterwards!
Most of the things I have played with in matlab should be done in linear data space, and I don't think there's any toolboxes already developed in matlab for stretching images that are quite as convenient as either Pi or photoshop.
If you do start fiddling in matlab you should definitely report your experiences here.
Cheers,
Andrew.
