Opening operation with a user defined NxN structuring element.

 

function call:

[out_img1]=vsg('OpenNxN',in_img1, conv_arr);

 

Arguments:

in_img1 mask image, 3 channel RGB, 1 channel greyscale or binary image, or DICOM image.

conv_arr – an integer array specifying the mask with which the input image will be processed.

 

Description:

Opening is a combination of erosion and dilation operations that have the effect of removing isolated spots in the image set A (in_img1) that are smaller than the structuring element B and those sections of the image set A narrower than B.

out_img1 – An image which has dimensions the same as the input image. This is the result of successive morphological erosion and dilation of the input image.

 

Example:

img = openimage('crown.jpg'); %color image

[out_img1]=vsg('Threshold',img,100);

figure;image(uint8(out_img1)); set(h,'Name','Threshold');

array = ones(3,3);

[out_img2]=vsg('OpenNxN',out_img1,array);

h=figure;image(uint8(out_img2));set(h,'Name','OpenNxN - binary image');
