Is there an easy way to remove all control points in a certain region?

I am spending a lot of time removing CPs from the sky and ocean. If there were a way to "stack" all of the images together so you could see all the CPs in a given region, it would make it a lot easier.
Or a way to create a mask and say "don't look for CPs in this quadrant"?

If an image is linked to more than just its neighbor, it compounds the amount of work.
Is there a way to do this more easily?

Cheers,

Re: Is there an easy way to remove all control points in a certain region?

AAIK the answer to your questions is no.

How many images are there in this pano?

Can you post a screenshot of the Efiror view withg layer mode slected so we can see where images are located and the preview of the pano?

We might then be in a better position to suggest how best to proceed.

Re: Is there an easy way to remove all control points in a certain region?

Well the best way to do it at the moment is to open the CP Editor, select the first image you want to remove all CPs from, e.g. #5, and shift+click the last image, e.g. #10. You will see all the CPs get displayed in the Links tab below. Now click on the first link in that tab, then shift+click on the last, and delete.

I would say the next best way is to click on the square link-box in the panorama editor window when the CP Editor is open but in the background... you know, the green, orange or red boxes (color depends on RMS quality), click on one and delete.

Both methods take a while to do in APP-1.* because APP loads the photos into the CP Editor each time which can take a second or two, or several on Linux. I haven't tried the GPU-enabled APG, but I assume it will work quite instantly there.

Re: Is there an easy way to remove all control points in a certain region?

To add a couple of points: there are two different kinds of things going on here:

1) removing the link between two images entirely - thus reducing the number of control points that you have to deal with at all

2) selectively removing CPs for the links that remain, e.g. from sky


1) is done in the Panorama Editor, as mentioned in an earlier post you select, with the mouse, the coloured box in the middle of the link you want to remove and press 'delete'

2) this is done in the Control Points Editor. Select, from the image list the two images in question - click and ctl-click to do that, then draw a marquee - in either of the images displayed, with the mouse to select the points you want to remove then press 'delete.'

Hope this is clear.

Re: Is there an easy way to remove all control points in a certain region?

Thanks guys.
Andrew, it's not a specific panorama I was talking about, this is a general workflow thing.
Example attached.
I have tried and done everything that has been suggested and often it is easier just to delete all the CPs and start from scratch.
I also often select all images in the CP Editor and sort by RMS and delete the worst ones.
What I was hoping for is the something like the ability to see all the control points at the same time on the stitched panorama or a stack of images. Then one could easily delete all the control points that are in the sky, for example.

Worth mentioning that, wthin the forum, the section called 'Future' is there for us to bid for enhancements - like the one you ask for here.

Posting there also gives another chance to draw the Kolor team's attention to your request!

Thanks Joe.
Kind of wanted to make sure what I was asking for 1) made sense and 2) didn't already exist.

The images you posted would cause APP's automatic CP detection system some problems.

There is not much in the scene which is not sky or sea! The auto CP detection system tends to cluster CPs around the middle/centre of the overlaps.

There is currently no way to tell APP not to place CPs on certain rareas of the images; sky or sea, for example. Nor is there a way to 'globally' remove CPs from certain areas of a series of shots.

I don't know what settings you are using for auto CP detection but in this case you may benefit from reducing the setting from High to Standard and reducing the no. of CPs to detect.

Makes sense to me (I've been asking for it for a while)

IMO, User input is important to APP  and they develop what people ask for.  So the more people who ask for this feature, the more likely it is to be done.
