To manually select pixels for grow-cut segmentation, you can use the roipoly
function in Matlab. This allows you to select a region of interest (ROI) by manually clicking on the pixels you want to include in the ROI.

In the code above, img
is the input image and num_slices
is the total number of slices to apply the segmentation to. The ischanged
function can also be used to check if the ROI has been modified between slices, and if so, update the bw
mask before applying the segmentation to the current slice.
