I'd like to use scikit to plot the size distribution histogram of particles 
in an image, which is similar with Adam's. I tried 
scipy.ndimage.measurements.label(image), which I thought would give an 
array about particle sizes. However, the output array is with all 1, 
obviously nothing about size. I must get something wrong...So which 
function should i call for the size distribution? Thanks Juan!
