MLT Algorithm Setting?

Hi Adam,

Really enjoying the workflow tutorials. I noticed though that related to MLT, you don't change the actual algorithm to MLT, you leave it the default Starlet Transform. What is the reason for that?

    I hadn't given it much thought. It was my understanding that because I was working on small scales (like the smallest to remove the 1st layer)- I didn't think there would be a difference. According to the rollover information, it appears it matters if I want to use a more refined layer scheme (instead of dyadic) and perhaps it is more important for large scale stuff...but for the larger scales I would use MMT instead. 

    I hope to create a tutorial on the uses of MMT and MLT (and perhaps the difference in the algorithm)- but in my usage I did not think it mattered. You might want to experiment and see if it makes a difference given the way I was using it (and let us know!).

    Hi Adam,

    In my OSC image of M33, in removing the 2 layers like your example in the workflow tutorial, there is a noticeable difference between the two algorithms. MLT is more subtle, ST does more smoothing and also dilates my stars a little more.

    Yes...but what is interesting... try the MLT with just the one single layer (1st one). :) I think you will discover why I use the Starlet as a default.
