ADAPTIVETHRESHOLD An adaptive thresholding algorithm that seperates the foreground from the background with nonuniform illumination.
bw=adaptivethreshold(IM,ws,C) outputs a binary image bw with the local threshold mean-C or median-C to the image IM.
ws is the local window size.

tm is 0 or 1, a switch between mean and median. tm=0 mean(default); tm=1 median.
