Connectivity in MATLAB

Create a checker board pattern and count the number of objects using 4 and 8 connectivity.

MATLAB CODE:

I=checkerboard(20);

figure,imshow(I);

[l,num]=bwlabel(I);                       % check the number of objects using 4 and 8 connectivity

RGB=label2rgb(bwlabel(I));   % Display the objects using conversion label2rgb

figure,imshow(RGB)

Checkerboard Pattern

Connected Components

CONCLUSION:

A checkerboard pattern was created and the connected objects were found using 8 - connectivity. All the connected objects were displayed using an RGB representation as shown in Fig. 1
