In Matlab Complete the following task:

Problem: Write a function named DeleteRegion that takes an input image and regenrates output images as given below.

Your function will be tested against two other images that are not visible to you, so hard coded values for structuring elements will not work.

$\%\%$

INPUTS:

$\%$ I $=$ input image

OUTPUTS:

Iout$\_$student contains all regions except the third largest region removed $($set to background $-0$ intensity$)$

Note:

$1)$ All ouput image are of datatype double

$2)$ All output images are same size as input

$\%$Test this function as below:

I $=$ imread$(\text{'}$Ex$\_1\_$Pb$\_2\_1.$png$\text{'})$;

Iout$\_$student $=$ DeleteRegion$($I$)$;
