Yes the directional symmetrical open is also very useful. Thanks.

Is there a way that the close function can work on a wider range. For example if a high value is given the maximum expansion is that value. Meaning it would still work if the blobs were closer.

I used I big dilate value because I was worried that if the blobs were further apart it would not close. What value do you recommend I use for this image width but the blobs were further apart (closer to the image edge).

My apologies. The close value I was using was way too high i.e. symmetrical horizontal close at value 14. I reduced it to value 4 and it is working as expected. Thanks

Dawson,

I tried the horizontal close on your image and it appears to do what we expected it to. (see attached). But perhaps you want something different? Can you change the image manually to what you'd expect it to do and we can then either adapt that module or recommend a different one.

Thanks,
STeven.

Hi STeven,

There seems to be an issue with the new feature. The directional close seems to effect blobs with specific orientation only instead of the direction of the close function. In the attached example, if you applied a directional horizontal close, the 2 bottom blows don't get joined. Only the vertical blobs seems to expand horizontally while the slightly diagonal blob remains unchanged or unaffected. Logically all blobs should expand horizontally irrespective of blob orientation.

Fantastic. Will give it a try.

Dawson,

That's been added to 2.48.22. Give it a try and see if that is what you needed. The result is a bit confusing since a lot of small lines are generated due to the strictly horiz or vert bias.

Note, we also updated the Open module too since its the symmetrical opposite to close.

STeven.

Hi Steven,

Is it possible in the Close module to have a feature that allows the user to close in either the horizontal direction or vertical direction only. This would definitely be a good feature. Thanks.
