morphclose_cvip() - perform morphological closing of a grayscale or color image.



[outImage, struct_el] = morphclose_cvip(inImage, kType, kSize, kArgs)

Input Parameters include :

Output Parameter include :


The function performs morphological closing of a grayscale image. Morphological closing operation is the combination of dilation followed by an erosion. The user can specify the kernel and its parameters, otherwise the default kernel and kernel parameters are selected.

% Read image

 I = imread('cam.bmp');

% Call function using default parameters

  O1 = morphclose_cvip(I);      %Square kernel with size 3

% Call function using user specified parameters

 [O2, kernel] = morphclose_cvip(I,3,5,[5 3]); %5*5 rectangle kernel with rectangle width 5 and rectangle height 3

% Display input image

 figure;imshow(I);title('Input image');

% Display output image

 figure;imshow(O1,[]);title('Output image using default parameters');

 figure;imshow(O2,[]);title('Output image user specified parameters');
