Is there a tool/script which can extract images (save them as separate image files) inside an image, each sub-image is separated by whitespace?

Sounds like a job for the montage command.
montage -tile 1 -geometry +0+0 *.jpg ../big.jpg
mogrify does batch processing so you could use something like this (change the font, size, color, position etc as per your taste):
mogrify -font Liberation-Sans -fill white -undercolor '#00000080' \
-pointsize 26 -gravity NorthEast -annotate +10+10 %t *.jpg
to add the file name without extension (%t) to all jpgs in the current dir, e.g. orca-lm-1.jpg:
This will overwrite your files so make sure you have backup copies.
If you use a different format (e.g. png) for the output files then the original files will remain unchanged:
mogrify -format 'png' -font Liberation-Sans -fill white -undercolor \
'#00000080' -pointsize 26 -gravity NorthEast -annotate +10+10 %t *.jpg

My Imagemagick scripts multicrop or multicrop2 will work on your image to separate them into 3 new images. Optionally you can unrotate them. They are Unix bash shell scripts and require a Unix-like environment. See my web site at http://www.fmwconcepts.com/imagemagick/index.php
You do not mention what OS you are using and if you have Imagemagick installed and what version that might be.
