Hi,
There is an auto crop plugin in Fiji.
Alternatively you could write a macro that just scans the image borders by
rows and columns, going towards the centre and stops when a row or column has
non-zero pixels. Then use those coordinates to define a rectangular region and
then use the Crop command.

Cheers
