"Write a MATLAB script to segment an image using $4$ different kernels, combine the segmentation results by taking the maximum of the absolute values, and then display the final segmented image after compressing the values to a $0-1$ range using an automatically detected threshold value."

The key steps to implement this in MATLAB would be:

$1.$ Load the image

$2.$ Apply the $4$ different kernels to segment the image

$3.$ For each pixel, take the absolute value of the $4$ segmentation results and select the maximum

$4.$ Compress the combined segmentation result to a $0-1$ range using an automatically detected threshold value

$5.$ Display the final segmented image
