Hi everyone,

  I'm new here and am not a mathematician (medical student...) yet I
have a question.
Suppose I have a lot of 2D images of a human organ in various states.
And I know black corresponds with high blood flow to an area.
An area in the organ consists of a list of pixels which are adjacent.

What I want to do is to obtain a measure of the blood flow in different
areas.
It should consist of a single value.

My needs are:
1. The algorithm should be sensitive to small bursts.
2. Can be implemented in MATLAB.

Calculating the mean value for an area doesn't work well - large areas
tend to reduce small bursts.
Calcualting the max is too sensitive.

Thanks for any help,
   Yaron
