Sobel function error in image
显示 更早的评论
I edit the code but again there is an error
I=imread('first palm.jpg');
subplot(1,2,1);
imshow(I);title('first palm');
BW1=edge(I,'sobel');
BW2=edge(I,'canny');
subplot(1,2,2);
imshow(BW1);
title('sobel edge detector image');
subplot(1,2,1);
imshow(I);
title('first palm');
subplot(1,2,2);
imshow(BW2);title('canny edge detector image');
and this error "Error in Edges (line 4) BW1=edge(I,'sobel');" appear to me

most of these are for gray scale images.
I suggest using "rgb2gray"

If you still care, is I an RGB image or gray scale?
