Convolve with a kernel rotating it 8 times and getting the absolute maximum value. \n
* Kernel must be square. \n
* The rotation is implemented only for kernel sizes 3x3, 5x5 and 7x7. \n
* Supports all data types except complex.
* Returns zero if the counter aborted.\n
* If the kernel image attribute "Description" exists it is used by the counter.
