Compute the filled convex hull.

 

function call:

[out_img1]=vsg('FilledConvex',in_img1);

 

Arguments:

in_img1 input image, 3 channel RGB, 1 channel greyscale or binary image, or DICOM image.

 

Description:

Consider a single blob in a binary image. The convex hull is that area enclosed within the smallest convex polygon which encloses the shape. out_img1 – an image of the same dimensions as the input image. The output has the smallest possible enclosing polygon drawn around the objects in the input image. The polygon is filled with white pixels.

 

Examples:

Img1 = openimage('A8.bmp');

h=figure;image(img1);set(h,'Name','Input Image');

[out_img1]=vsg('Threshold',img1,100);

[out_img1]=vsg('ConvexHull',out_img1);

h=figure;image(uint8(out_img1));set(h,'Name','Convexhull Image');
