function bw=adaptivethreshold(IM,ws,C,tm)
%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.

Original Image After Segmentation
My modified code for testadaptivethresh.m

im=imread('nfliver7.gif');
figure,imshow(im)
bwim1=adaptivethreshold(im,300,-0.15,0);
bw=bwareaopen(bwim1,3000);
se=strel('diamond',4);
er=imerode(bw,se);
bw1=bwareaopen(er,3000);
er1=imerode(bw1,se);
bw2=bwareaopen(er1,1000);
fi=imfill(bw2,'holes');
figure,imshow(fi)
op=uint8(fi);
seg=im.*op;
figure,imshow(seg)
imwrite(seg,'sliver7.jpg');
