Error using ==> iptcheckinput
Function EDGE expected its first input,I,to be two-dimensional.
Error in ==> edge>parse_inputs at 541
iptcheckinput(I,{'numeric','logical'},{'nonsparse','2d'},mfilename,'I',1);

edge函数不能接收二进制图片~若是图片格式为.tiff就直接可以用~
二进制图像可以使用bwperim,但是是寻找图像的周边的.
如果你一定要使用edge函数,可以使用double强制把你的二进制图像转换成double型的.
例如：
Ijpg = imread('1.jpg'); %读取图像
BW1=im2bw(Ijpg,0.95);
BW2=double(BW1);
BW3=edge(BW2,'sobel');
