I wish to skeletonize this image
To do so i am using matlab's bwmorph
function, Here is the snippet :
bw = bwmorph(img_bw,'skel',Inf);
However the output is not as expected. Here is the output.
Could someone suggest a better way to achieve proper results ?
EDIT: here is a stripped down relevant code
img = imread(name);
img = rgb2gray(img*4);
img_bw = img > 50;
img_bw = medfilt2(img_bw,[10 10]);
bw = bwmorph(img_bw,'skel',Inf);
What you see is aliasing, the imshow
function can not display the full image because it is to large to fit the screen. To fit the screen some rows and columns are skipped, which cause the lines to be disconnected. To display an image at full resolution using a scrollpanel, use imscrollpanel
hFig = figure('Toolbar','none', 'Menubar','none');
hIm = imshow(bw);
hSP = imscrollpanel(hFig,hIm);
