Hello people!
I need help with two things
1st off – I have an image, a piece of duodenum which i need to convert into areas by colour i.e. instead of having a full colour picture i need a silhouette of the tissue and also i need to identify the non-tissue areas with other colours such as white and green, so in effect going from a 256 colour image (or whatever!) to essentially a 3 tone image with the piece of duodenum in black, but i’m not really sure how to do it.
Secondly, once i get those areas defined I need to convert the area covered by each colour into a percentage of the whole area of the canvass so i can get a numerical output from a picture source
(i.e. there are 40,000 black pixels, 20,000 whit pixels and 4,000 green pixels in a document of 64,000 pixels = 62.5% black, 31.25% white and 6.25% green)
Plz help me or point me in the right direction, I work for your National Health Service and i’m trying to pioneer a technique that may make a certain diagnosis more accurate, but i have limited photoshop skills
Thanks in advance
