I tried multicrop script on cygwin. After it excuted, there is no output files.

$ multicrop -f 10 -u 2 3ladies1.jpg lady.jpg

You use "-u 2" which, as the script says, calls Fred's unrotate script. The error message "unrotate: command not found" suggests you don't have that.

Thanks. I misunderstand the exsample. Now it works.

It takes about 10 mins to divide a 5800*8000 jpg which include 3 pics. How can I accelerate the process?

See https://imagemagick.org/script/architecture.php. Its likely you ran out of heap memory so the image pixels are pushed to disk. You can verify by adding -debug cache to your command-line. The debugging output tells you where the cache resides (e.g. memory, disk, etc.). On our 32GB system, we cropped 3 slices from 1 5800x8000 JPEG image, and it completed in less than 1/2 second. The performance suggests that the pixel cache was hosted in memory rather than disk.

1/2 seconds vs. 10 mins

I should seriously consider upgrading the memory.
