Hi, After decomposing binary image into different connected components, I want extract each connected component and split a connected component if it has particular number of pixels in it. So that total number of connected components are increased....Is there any way to do that...

Sure. Just loop over CC(i) and use the CC(i).PixelIdxList field to determine the number of components and to apply your splitting criterion. At the very end, modify all the CC(i).NumObjects values.

Thank You All

Sir, one problem occurred , You have taken example of dividing a connected component into two, How we can do for general (e.g. 3,4,5,....), becuase in pixelhalf1 = pixellist(1:floor(end/2)); pixelhalf2 = pixellist(floor(end/2)+1:end);

How we can tune above statements..

在 MATLAB Online 中打开

        pixellist = CC.PixelIdxList{k};
        pixelhalf1 = pixellist(1:floor(sizes(k)/2));
        pixelhalf2 = pixellist(floor(sizes(k)/2)+1:sizes(k));
        CC.PixelIdxList{k} = pixelhalf1;                 
        CC.PixelIdxList{k+1} = pixelhalf2;

But it is not reflected in original image......
