Skeleton limb end detection from a binary image based on a 3x3 region.
function call:
[out_img1]=vsg('LimbEnds’,in_img1);
Arguments:
in_img1
input image, 3 channel RGB, 1 channel greyscale or binary image, or
DICOM image.
Description:
The LimdEnds function employed predefined masks for detecting 3×3
section end points. Once, detected, these limb end points are replaced
by a single white pixel. Otherwise the output pixel is set to black.
out_img1 - An image which
has dimensions the same as the input image. The output image displays
the limbends of the white regions of the input image.
Example:
img = openimage('A.jpg');
[out_img1]=vsg('Threshold',img,100);
[out_img1]=vsg('FullThin',out_img1);
h=figure; image(uint8(out_img1));set(h,'Name','Full Thin');
[out_img1]=vsg('LimbEnds',out_img1);
Notes:
1. For DICOM images, the function operates on each slice separately.
2. For RGB images, the function operates on each channel separately.
