using OpenCV write a C$++$ program with $($GUI$)$ to implement all Image segmentation techniques.

Your program should provide the following functionalities:

$1)$ Open and read the image in gray$-$scale

$2)$ Apply all segmentation filters and techniques

$3)$ implement a user$-$defined filter $($allow the user to design his own filter by specifying the size and coefficients. Then, apply it on the input image$)$

$4)$ Export the enhanced image and save it$.$
