Help requested: Pixel area counting with "magicwand&quo
Posted: Wed Jan 12, 2005 5:23 pm
I am working on digital images of brain sections and I need to know the area of observed degeneration. I can select an area of similiar color and intensity by using the magicwand tool which is very helpfull (as other programs require me to first transform the image into a threshold). However, problem is Photoshop does not give a readout of the total number of pixels (area) that has been selected using the magicwand (or any other selection tool.)
Is there any way I can get that information, and also get a output file as tabbed text file?
I am in desperate need for this and i belive this is not a very tough problem to crack, however as I lack any formal training and experience in programing I have basically hit a wall.
I can get around this problem but the thing is I have to handle about 300 (1360X1024pixel) images per sample and doing it in a roundabout way will take me days to calculate the individual areas manually for a single specimen.
I would appreciate any hints to solve this.
