>> edit im2bw
and you'll have your answer. That's the sourse code for the function. Basically it converts level to the range that the data class is in and then thresholds like bw=input>level.

So level is the threshold. Any pixel with intensity greater than the threshold is equal to 1 and pixels with intensity smaller than the threshold are set to zero. No equations its a logic process.
