My best guess is that your sort does not work the same as mine. Test this: convert BW.jpeg -threshold 50% -type bilevel \ -define connected-components:verbose=true \ -define connected-components:area-threshold=2000 \ -connected-components 4 \ null: | awk 'NR>2 {print $2}' | sort -g -t "+"...

Yes. I have all those tools.

I'll try to test on a ubuntu machine, but at the end the final solution I will need to run it on cygwin. So. I'll need understand the logic in your code.

Thanks snibgo.

It seems to work pretty fine. Only some few pixel are still green. I remove the fuzz and more pixel become green, so is not the fix needed.

Besides that, how mix both commands to have a a single command to do this?

Thanks again.

I've sent the first part in this way convert in.png \ -fuzz 20%% \ -transparent '#4CFE00' \ -alpha extract -negate \ -threshold 50%% \ ( +clone \ -define morphology:compose=Lighten \ -morphology HMT 2x3+0+1:0,0,1,-,0,0 \ -morphology HMT 2x3+1+1:0,0,-,1,0,0 \ -negate \ ) \ -compose Darken -composite ...

I've been able to do the first 3 steps snibgo suggested. Now, I dont know how to do the last step. A masked composite over the input. A way to approach the problem is: 1. Convert green pixels to white, and everything else to black. 2. From that, turn black all white pixels that have a black pixel ab...

I'm running the bash commands on Cygwing (like a linux terminal emulator) under Windows 7.

Yes. Snibgo told me to attach the input PNG ensuring that was not a JPEG. I'm confused what you need.

$ convert -version

And testing on Cygwin.

Attached again

Attaching again input.png from Dropbox. I hope this time has the correct format.

Below you see that I have the BW.JPEG and input.JPEG and the images generated are different than yours. For example Box1 is not joined with Box2 https://ai8fqg.ch.files.1drv.com/y4mmBzZ9F0olPampFoi9qCEJnifgtAexzhc8igyDYKTLhjs9SOO3jk3A-pogyAPTNVQJbNgDCB7Mi3X3012rzBb56Czlna8uwIMs_BYJMHqzMWWj28_hhFb5CD...

Thank yout for help and time fmw42 and that great script., but I;m not sure why for me is not working correctly. The image0 is the same as yours. Your image1 is created as image3 in my side. and the boxes are generated in individual images (image1, 2, 4 and 5). Additionally is creating the images wi...

I have saved as PNG. How can be sure not a JPEG?

Hi snibgo, Thanks for the ideas. I was able to reach the step 3 of your suggestion, changing to purple only those regions I want and rest is black. Now from here how can I do the mask to mix this purple and black image with the original input? This is what I have so far: areas=$(convert input.png \ ...

Hi Bonzo, The green areas are not only on the top. The green lines I want to isolate have 1 pixel heigth. If there is way to identify these lines to change the colors only tho the lines to diferentiate from the rest of green areas, or replace colors of green areas except the 1 pixel lines. A more re...
