MATLAB: Fill the spaces between circles

circlefillMATLABplot

Hi,

I need help to understand how to fill the spaces between lines.

I have 5 circles with this disposition:

I would like to obtain the following picture as a result, but I can't understand how:

How can I do this? I have plot the circles using the function "viscircles".

Thanks!

just a quick look, but maybe the shaded regions are shared by exactly 2 or 3 circles, not more and not fewer...does that work? as for algorithm to fill that region, maybe takes more thought (assuming above is even correct).

I believe you can set the label to be the same. For example, make blob 3 have a label of 2 and then blob 2 will now be the old blob 2 and the old blob 3

labeledImage(labeledImage == 3) = 2;  % Merge blob 3 into blob 2.

Now call regionprops

props = regionprops(labeledImage, .........

MATLAB: How to plot (n) circles with known center and radius

If you have the Image Processing Toolbox, use viscircles(centers, radii):

theta=10 % azimuthal distance between the centers of circles group
r=120 % The radius of the big circle
DM=12  % The radius of the group of circles
numCircles = 38;
for k = 1 : numCircles  % number of circles
	xCenter(k) = r * cosd(90-(k-1)*theta); % the x comoenets of the circle group
	yCenter(k) = r * sind(90-(k-1)*theta); % The y component of the circle group
end
plot(xCenter, yCenter, 'b.');
grid on;
viscircles([xCenter(:),yCenter(:)], 15 * ones(numCircles, 1));
axis square
