morph_hitmiss_cvip() - perfoms morphological hit-miss transform of a binary image.



[outImage] = morph_hitmiss_cvip(inImage, hitmissFilt)

Input Parameters include :

Output Parameter includes:


The function performs morphological hit-miss transform on a binary image. If input image is a color or gray-scale image, binary thresholding is performed before the hit-miss operation. The hit-miss filter is a structuring element containing 0's, 1's and NaN's or "don't care". Don't care element is represented by NaN value in this case. And, don't care elements in the structuring element match with either 0s or 1s.

% Read image

 I = imread('shapes.bmp');

% Call function using default hit-miss filter

 O1 = morph_hitmiss_cvip(I);

% Call function using user specified hit-miss filter

 kernel = [0 0 0; nan 1 nan; 1 nan 1];

 O2 = morph_hitmiss_cvip(I,kernel);

% Display input image

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

% Display output image

 figure;imshow(O1,[]);title('Output image using default hit-miss filter');

 figure;imshow(O2,[]);title('Output image using user-specified hit-miss filter');
