Run garbage collection

Is it possible to run garbage collection on a particular instance of a class?

I am manipulating JPG images (rotate, etc). This uses a LOT of memory when processing (about 9Mbytes for a 3MByte image). Once I am done with the image, all the resources used can be garbage collected.

GC does run when the memory usage gets near 90%, but I would rather it be part of the image processing, that is process the image and right away recover the memory used.

I know I can request that the JVM run GC overall, but can this be done on a particular object?
