I want to ask, I hope you see this can help me, thanks I've done segmentation on that image and has 9 parts segmentation, I just want to take segmentation to figures 5 and 6, but I can only take segmentation in figure 5.
I want to ask how to combine figure 5 and figure 6 on the one axes as the final result of segmentation ..
note: I only use one image only, "Lat1.bmp" and I want to know how to combine the two figures on the one axes as the final result of segmentation

I may not understand the question, but why not just use segmented portions 5 and 6 as a mask on the original BW image? I guess the workflow would be something like
- extract the segments
- make an image of "falses" the same size as the original called BWsegs
- set the indices of segment 5 as "true" in BWsegs
- set the indices of segment 6 as "true" in BWsegs
The BWsegs is what you're looking for. You can use regionprops to get the bounding box for cropping if you'd like.

you can see image "hasil akhir segmentasi" ? it is the final result of segmentation. I want to combine the figures 5 and 6, and displays it on "hasil akhir segmentasi". But I do not know how to combine figure 5 and 6 into a single figure

It looks to me like Figure 5 = "hasil akhir segmentasi". So you know how to extract Figure 5. It also looks like you know how to extract Figure 6. So just extract them (without cropping them) and use
single_fig = Fig5 | Fig6;
Then you can crop that if you want.

Did you solve this since you posted this? It's marked as Accepted so many people are ignoring it.
To combine 5 and 6, don't crop and just OR them together.
