Nearest Neighbor Interpolation

This is the fastest and least accurate interpolation mode. The pixel value in the destination image is set to the value of the source image pixel closest to the point
(
x
S
,
y
S
):
D
(
x
D
,
y
D
) =
S
(round(
x
S
), round(
y
S
)).
To use the nearest neighbor interpolation, set the
interpolation
parameter to
IPPI_INTER_NN
or use the functions with the
Nearest
suffix (pass
interpolation
=
ippNearest
to
GetSize
functions).

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.
