If your camera doesn't move much it might be possible to only calculate the mask once in a while since trees don't typically move much either. This could be done every 30 seconds or so and saved as a Marker which is used to mask the final image. That would save you a couple steps and increase the fps.

Also, check if you can't use a smaller image. Planes are quite big in the image so scaling the image by 2x would still work and be 4x quicker.

I probably incorrectly expressed. I need to remove the blobs that touch the edges and which are in 30px around the first. Now I solve the problem with Dilate and Math modules, but this reduces performance. I thought that if I will combine it into a single operation, will be able to increase FPS.

Yes, that is possible. The blob filter is one way to do this. You could also just draw a white rectangle around the border of 30 px thick (using Display_Rectangle) and then remove the largest blob.

If you include an example image we can show you how this could be done.

Blob filtering

Tue, 30 Nov 1999 00:11:00 EST

I would like to filter blobs so that remained only those that are further at least 30px from those blobs that touch the edges of image. So I want to leave the plane on a background of the sky, but to remove the branches and leaves of trees. Can this be done using the Blob Filter module?
