i am trying to mesure or count pixels in this photo but i want to calculate only white pixels
any one can help please ?
What is meaning “white pixel”?
If it meaning is “maximal value”, you just open the Histogram window.
And then push the List button.
Is this a solution?
because your image is binary, the mathematics is easy. Either
- Measure with “Area” and “%Area” checked in “Set Measurement…” and multiply the Area-value with the percentage
- Measure with “Area” and “Mean” checked in “Set Measurement…” and multiply the Area-value with the Mean-value and divide by 255
For this image
I get the measurement-values
and with these I get the number of white pixels which is about 2800.
