Re: Get coordinates Top, Left, size of some areas

I was able to remove the unwanted regions of big boxes filtering first all those regions that have 45 pixel height and changing those regions to black.

Now my script looks like this:

Maybe if you have time, you can help me to optimize my script to avoid the use of temporal images that are not needed.

Code: Select all

toremove=$(convert input.png -threshold 50% -type bilevel \
-define connected-components:verbose=true \
-connected-components 4 \
null: | 
awk '/x45/{
sub(/x/, "+", $2)
split($2,b,"+")
printf("%sx%s+%s+%s\n",b[1]+2,b[2],b[3]-1,b[4])
}')

#Here I copy input to use it in loop below
convert input.png out.png  

#Now in this loop I colorize to black 4 regions and I use as input and as output the same out.png. Is there a better way to do this?

for region in $toremove; do
    convert out.png -region $region -fill '#000000' -colorize 100 out.png
done

convert out.png \
-transparent '#39D6AE' \
-transparent '#9EB629' \
-transparent '#8DA718' \
-transparent '#A47721' \
-transparent '#BD8B2B' \
-transparent '#EEEEEE' \
-transparent '#B4CEF8' \
-alpha extract -negate \
-threshold 50% -type bilevel \
-define connected-components:verbose=true \
-define connected-components:area-threshold=2000 \
-connected-components 4 \
null: | awk 'NR>2{print $2}'

Code: Select all

423x310+530+634
422x310+70+634
423x160+530+424
422x160+70+424
423x155+530+193
423x145+70+203
264x40+680+109
Thanks again
