Title: Background Enhance Script
Post by: Silvercup on 2010 May 14 01:00:31

Hello:

I spent a couple of days on Pixi Script, and you already have an early version of Background Enhance  Script (based on m27 tutorial processing secuence) .

(http://farm2.static.flickr.com/1002/4606096290_e4e48dc2e6_o.jpg)

Although it is very intuitive I'll explain a bit how it goes:

Running the script opens an imagewindow where we do all "previews" and the script window opens to the left.

We can zoom with the mouse wheel and use the Zoom to Fit, Fit View and ZoomtoOptimalFit to adjust the size of the window (thanks to Nikolay).

Under "Enhancement parameters"

Small Scales Layers  are small-scales that are going to be deleted to form large-scale image.
Scales Small Amount is the amount that we will highlight the small scale to prevent potential artifacts due to stars or bright objects that can produce halos.
Amount is the amount by which the image is mixed with the original scale.
Mask Amount is the amount that we will highlight a mask to protect the bright areas of the image.

Preview button: performs all operations of "Background Enhance" and displays it in the "preview ". May take some time depending on the image.

Extract Images: Marking the options extract  large-scale, small-scale or mask images.

Show images: Clicking on each button we see the corresponding image.

Hope reviews and see your results before and after.

Best. Silvercup

That looks like a very well-formed script - well done

I'll be having a closer look at this when I get back to my PI machine - I am keen to see how you have implemented some of the functions, as I have an idea than could take advantage of some of your hard work :D (sorry, but it is the easiest way for me to learn, and I will ensure credit is given where due ::))

Cheers,

Hello Silvercup,
Tested your script in some images, it work just fine.
Standard settings are doing a fine job in most of my test.
Great piece of script, thanks to take the time to do it.
Cheers

Antoine

Hi Silvercup,

Very nice, and works well....my only request would be for a defaults reset button.

Well this is pretty darn neat!  Needs to become a regular PI tool IMO.  Although the script runs fine.  Thanks for your work on this!!

Hello Silvercup, thank you for nice script.

Small trick:
Instead for(var i=0;i<11;++i) {Preview.zoomIn();} you can use Preview.zoomFactor=11;
Also I found solution to avoid 'strange' movement of green rectangle:

Code: [Select]

      var busy = false;
      onMouseMove = function(x,y)
      {
         if (this.busy) return;
         this.busy = true;
         Preview.setViewport( x*w/Size, y*w/Size );
         repaint();
         this.busy = false;
      }
Best regards,
Nikolay.

Hi, very nice script.

I wondered, why I did not see it in the Menu entries. So I started it "per hand".
If you like, you could add this line to your script:

#feature-id    Utilities > BackgroundEnhance

So - this was my first try in understanding Javascript in PI  ;)
