Hi Louise,

It can be done easily enough. I use the Fiji distribution of ImageJ (www.fiji.sc) so i am not sure if the functionality is available in the standard imagej package but the following worked for me

1. go to Image --> colour --> colour deconvolution
2. choose H AEC as te vector and press OK
3. you should get three images. Select the red channel one (Colour_2)
4. go to image adjust threshold, Make sure dark background is unselected. Adjust the threshold (or the MaxEntropy auto setting seemed to work ok).
5. Measure the image (Analyze --> Measure)


If you want a macro for doing this let me know


Cheers

Cam

Subject: Quantification of red in bright field image

Hello,



I`d like to quantify the amount of red in this histo slide using ImageJ. I
am not experience with microscopes and I´m not sure where to start. I
searched the ImageJ archives but everything seems to be for fluorescent
images and not brightfield.



Any help would be great!



Thanks



Louise
