General - Pixel coplor analysis - Where to start from

I would like to create a website (PHP5, LAMP) which analyse specific fave photos. The pictures are only showing vascularisation of the face. I would like to scan each pixel of the photo. Be able to detect the average quantity of REDs (probably a range - see attachment) and compare this one to a population mean value. I would like to display something like

Percentage of REDS: 35%
Having the mean value for the population being 40%
I would then be able to display: You are under the average value

Image on: www . cadic . com / modelface .jpg

I wonder where to start from
Can I used GD are ImageMagik PHP classes ?
Is OpenCV usefull ?

The must would also to be able to detect the cheeks area automatically and make the calculation only within this area .

Can someone help me with a starting point ?
