img = imread('whiteBG.jpg');
img = rgb2gray(img);
figure, imshow(img)
% count the pixels of each bin
[counts, bins] = imhist(img);
[M, I] = max(counts);
tempImg = img;
% we know that max pixels in image are white so change all pxiels in that
% bin and above to zero
tempImg(img >= bins(I)-1) = 0;
figure, imshow(tempImg)
% clear some traces or blobs having area less than 30 pixels ...
% (can change according to requirement)
BW = bwareaopen(tempImg,30);
figure, imshow(BW)

It looks reasonably well cropped right now. Why do you need to chop off a few pixels more? What's the need? I think you can do what you need to do without cropping to the bounding box, so why bother?

I already told you what to do next if that didn't work: "If that doesn't work you can......". See my above comment.
