This is a shot in the dark since I'm not sure exactly what you're doing (it's probably over my head).

You want to detect pulses that have a range in amplitude of [1, 255]? There can be pulses with various amplitudes that overlap at the same time?

Could a fourier analysis help you tease apart the pulse waveforms? Are the pulses periodic in any way?

Would an envelope follower help you track the pulses?

Anyway, just throwing stuff out hoping it helps. Good luck.

startpoint = start point of fill
startcolor = color of pixel at startpoint

fill(startpoint, fillcolor, startcolor);

fill(point p, color fillcolor, color startcolor)
{
  if (p.color != startcolor)
  {
     p.color = fillcolor;

     // fill the surrounding four pixels
     fill(point(p.x+1, p.y), fillcolor, startcolor);
     fill(point(p.x+1, p.y+1), fillcolor, startcolor);
     fill(point(p.x-1, p.y), fillcolor, startcolor);
     fill(point(p.x-1, p.y-1), fillcolor, startcolor);
  }
}
