how i could obtain connected component gray scale with format that diffrence the percentage of gray

[diegomage]

i have this image


when i use this code i obtain

Code: Select all

 convert fragresultc.png -define connected-components:area-threshold=0  -define connected-components:verbose=true  -connected-components 8   tmp.png >  data.cc

Code: Select all

Objects (id: bounding-box centroid area mean-color):
  0: 242x330+0+0 132.6,99.5 28190 gray(0)
  2: 192x279+24+51 122.9,167.5 11332 gray(1%)
  104: 136x160+59+167 126.8,245.3 11064 gray(75%)
  1: 165x300+69+30 176.1,146.4 6022 gray(1%)
  24: 90x245+0+85 46.4,217.8 5201 gray(17%)
  134: 59x108+0+222 22.1,281.5 4085 gray(96%)
  135: 75x82+88+248 126.6,288.7 2164 gray(97%)
  32: 62x80+145+102 172.2,136.6 1908 gray(23%)
  11: 78x58+132+71 166.2,103.1 1237 gray(8%)
  123: 54x44+16+191 37.8,215.7 1232 gray(88%)
  36: 42x28+86+105 104.9,117.9 800 gray(26%)
  138: 69x14+91+316 125.5,323.4 780 gray(99%)
  27: 51x32+53+88 74.2,103.5 728 gray(19%)
  47: 24x41+56+123 67.5,144.0 656 gray(34%)
  136: 36x43+112+273 127.3,298.1 444 gray(98%)
  137: 25x26+117+284 128.2,299.1 440 gray(99%)
  106: 35x25+173+168 193.6,182.2 396 gray(76%)
  101: 32x30+44+164 61.0,175.6 383 gray(73%)

i need to obatin the color in format similar to this

2: (50919,50919,50919) #C6E7C6E7C6E7 gray(78%)
3: (51391,51391,51391) #C8BFC8BFC8BF gray(78%)

for recognizing the diffrence in gray of same percentage

add -define connected-components:mean-color=true

See https://imagemagick.org/script/connected-components.php

i add but obtain the same results

catn get difference between percetange gray

[fmw42]

It has to be added before -connected-components, the same as the other -define.

Perhaps I misunderstand. That define makes the output resemble the input after doing area filtering.

What is that you want. The text data will not be in the format of txt:. This is the only format. It will not show pixel coordinated, nor raw color values, nor hex values. Only gray() or srgb()

If you do not threshold, you will get the same output as the input when using mean-color=true, since your regions are constant colors. So there will be no change or difference. If your input is JPG, then compression will cause some fluctuation in color and the output will be slightly different from the input depending upon if you have used a fuzz value or not.

Once you do area-threshold other than 0 and mean-color=true, then you can do a compare of the input with the output using compare or with -compose difference -composite.

i need gray with more decimal like gray(98,51%) because some gray color are repeat and not are the same colors

[diegomage]

this are repeated and not the same color have less 1% of difference

2: 192x279+24+51 123.0,167.2 11352 gray(1%)
104: 136x160+59+167 126.8,245.3 11052 gray(75%)
1: 165x300+69+30 176.1,146.6 6010 gray(1%)

There is no current control over the decimal place. You will need to ask on the Developers forum for an enhancement.
