Priority level set

[jene2in]

Hi,

I am new to matlab and I was wondering if I can get some tips to a step in matlab.
The goal of the project is face detection using Fast Marching method. The algorithm has a step where we need to find the face pixels. I am able to extract the face pixels and the resulting image is in YCbCr format. The next step is to set the priority level such that:

h(F(x,y))= 0 if I(x,y) belongs to priority 4
= 0.33 if if I(x,y) belongs to priority 3
= 0.66 if I(x,y) belongs to priority 2
= 1 if I(x,y) belongs to priority 1

so that Fast Marching Method propagates through the image depending on the speed function F at each pixel image. The speed function varies between the priority level. I would like to know what is a good command to set the priority level.

I hope I make sense and will appreciate any help. Please let me know if there are any questions.

huh? Why wouldn't you simply assign the priority to a variable?
