How to change boundary width in Active Contour Method?

Hi, I am writing a code, where I am using active contour method for segmentation. The relevent part looks like this:
bw1=activecontour(image,B0,iteration,'Chan-Vese');
Where B0 is the area on which the segmentation is to be performed, ieration is number of iterations.
the output is shown by the lines,
imshow(image)
hold on
visboundaries(bw1);
hold off
When I run the code for this image,

The output is like this:

But as you can see, the red boundary line is too thick and has white around it. I want to make the line thinner with no white around. How do I do it?

Call visboundaries with an output argument. That output argument will be an hggroup object containing two lines. You can then manipulate properties of the two lines directly. Here is an example:
I = imread('toyobjects.png');
mask = false(size(I));
mask(50:150,40:170) = true;
bw = activecontour(I,mask,200,'edge');
imshow(I)
hold on
h = visboundaries(bw,'Color','r')
hold off
h.Children(1)
h.Children(2)
h.Children(2).Visible = 'off';
h.Children(1).LineWidth = 1;
