Kernel version from image file

[Stephan A Suerken <inf222@Fh-Worms.DE>]

Hi,
        
 suprisingly I can't find a recommended way to extract the kernel version
from a kernel image file. Any ideas?
        
Thanks,
        
Stephan
        
P.S.: At the moment I use

function kernel_version_from_file
{
    if test -e $1;
        then strings $1 | grep -i "^[[:digit:]+]\.[[:digit:]+]\.[[:digit:]+]" | cut -d' ' -f1
        else echo "None."
    fi
}
