How to recognize...?

Hello, I am new on Image J, and I need to measure the color areas on my interest on a given picture, to compare treated vs control images.
After clicking “List” on a RGB histogram, I get the whole surface values for each color of the photo, from 0 to 255. It happens that it is hard to determine which ones are the values matching the interest areas, and which ones aren´t. Several years ago, with the Commodore Amiga there was a software that, when clicking on a given value of the histogram, it blinked in red in the picture, showing there the matched areas. Is there any possible way to do something like this with Image J, by clicking on values of the Histogram? I don´t like to use gray scale pictures, since the values might be mixed, and I am unable to recognize which ones belong to interest areas and which ones doesn´t.
It would be very important in order to determine the surface area of interest values, since I could change the similar color to the noninterest areas, thus permitting me to measure only those ones I need.
Thanking you in advance, sincerely
Naly

Re: How to recognize...?

Hi Clair,

I had a similar problem and added a utility: ColorReplacer to the
ShapeLogic plugin.

Select ColorReplacer and in the dialog enter the target color value
and the color distance. It will turn all pixels that are close than
the color distance into black and the rest into white if you select
the mask option. Then you can use the histogram to see how many black
pixels you have.

There is probably a simpler way to do this. Say use DeluxePaint on the Amiga.

Dear Sami,
Thank you very much for the material sent.
Now, I have to learn how to use it. :-)
The program I said before was the Butcher's 2, and not DeluxePaint
That was great. Unfortunately, I don´t have the Amiga any more. What a good machine it was! I suffered alot when it was discontinued.
Sincerely,
Clair

new Versatile Wand version with color support

Hi everyone,

for all those longing for some good old programs or computers - maybe
today's ImageJ is even nicer?

The 'Versatile Wand' plugin now supports color, and you can even select
whether it is more sensitive to brightness or to color hue. You can also
select 4-connected, 8-connected or non-contiguous modes, and, of course,
there is preview...
