Zero crossings edge detector.
function call:
[out_img1]=vsg('ZeroCross',in_img1);
Arguments:
in_img1
input image, 3 channel RGB, 1 channel greyscale or binary image, or
DICOM image.
Description:
out_img1 - An image which
has dimensions the same as the input image. The output image is the
zero-crossing edge regions of the input image.
Example:
img = openimage('lake.jpg');
h=figure;image(img); set(h,'Name','Input');
[out_img1]=vsg('ZeroCross',img);
h=figure; image(uint8(out_img1));set(h,'Name','Zero
Crossing');
