I = imread('circuit.tif');
BW1 = edge(I,'prewitt');
BW2 = edge(I,'canny');
BW3 = edge(I,'sobel');
figure, imshow(BW1)
figure, imshow(BW2)
figure, imshow(BW3)
Or you can choose manual threshold like,
BW1 = edge(I,'prewitt',0.4);
BW2 = edge(I,'canny',0.4);
BW3 = edge(I,'sobel',0.4);
figure, imshow(BW1)
figure, imshow(BW2)
figure, imshow(BW3)

I = imread('circuit.tif'); imshow(I) BW1 = edge(I,'Canny'); BW2 = edge(I,'Prewitt'); imshowpair(BW1,BW2,'montage') I = gpuArray(imread('circuit.tif')); BW = edge(I,'prewitt'); figure, imshow(BW)
