How about the following script?
I = imread('1.jpg');
BW = imbinarize(I);
BW1 = bwconvhull(~BW);
s = regionprops(BW1,'BoundingBox');
I2 = imcrop(I,s.BoundingBox);

During your copy&paste, a space seems to be mistakenly inserted.
Correct input:
s = regionprops(BW1,'BoundingBox');
Wrong input:
s = regionprops(BW1,'BoundingBox ');
