Use Signed Integer Data Types

Many image-processing kernels operate on
uchar
input. To avoid overflows, you can convert 8-bit input values and process as
16
- or
32
-bit
integer
values. Use signed data types (
shorts
and
ints
) in both cases, if you need to convert to floating point and back.

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
