WBPP & Binning?

Hey Folks,

Wow... this must be easy, but I can't figure it out.... how can I use WBPP to register my x1 and x2 binned data separately w/o running WBPP twice, once for each binning mode?  There's gotta be a switch somewhere but I haven't found it yet.

Thanx tons n' try not to laugh !!

    Hi James,

    Yeah binning and WBPP have a special rule. Basically WBPP honors binning as a feature of an image in its logic. This means WBPp will not naturally integrate images in the same filter group with different binning. There are some technical reasons for this. 

    WBPP *will* register images of different binnings IF they are in different filter groups. So I often do LRGB images where the L data is 1x1 and the RGB is 2x2. If an L frame is chosen as the registration reference, the RGB data will be upsampled/aligned to the L and at the end the integrated images of L,R,G,B will all be the same size (as the L 1x1). 

    You didn't state it... but perhaps I can assume you are working with OSC data? OSC data is basically like it is a single filter group (no filter). So the rule is, it will treat it differently. 

    But, you can spilt the work as you know in to steps. Yes, you will be running the script twice with a break in there... but it isn't too terrible. You would just to the first bit of WBPP with calibrate only. Then you would run WBPP again, but only the post processing part. Then you can choose a reference frame of 1x1 and the other frames will be aligned... and continue to go from there until you get integrated data.

    After I asked the question, I thought I had an answer...  I entered 'binning' in the keywords to split data by and set it up to be only post processing... I'd already run WBPP once w/o this set and my bin2 RGB was upsampled as an L was chosen as reference the first time... (this isn't OSC)... the second time the RGB was still not registered and integrated at it's natural bin2 state... I'd also set 'auto by binning' under the registration parameters...  anyway, not sure I'm making sense... still working on the first cup of coffee....
