Sorry to disturb you. I wonder is there any function in the vxl which can resize the images by using
the nearest-neigbor interpolation or bicubic interpolation,    such as 
void resize(const vil_image_view<vxl_byte>& src,  vil_image_view<vxl_byte>& dst);
The function resize resizes image src so that it fits exactly to dst.
I will appreciate if you can give me a help.
Thank you very much!
