Compatibility Considerations
If you have a transformation structure (TFORM) saved from an older version, you may
want to regenerate it from control points to get improved performance.
IPPL Not Used on 64-Bit Systems
Certain functions in the Image Processing Toolbox, such as the image arithmetic
functions, use the Intel Performance Primitives Library (IPPL), if it's available. (See ippl
for more information.) Note that these functions do not use the IPPL on 64-bit systems.
