8-bit Signed images

Purushoth — Mon, 04 Nov 2024 06:10:13 GMT

I have been using the following functions from intel IPP c++ library,

ippiCopy

ippiMirror

ippiMinMax

ippiScaleC

None of the above functions except ippiScaleC function has support for Ipp8s datatype support. Is there any particular reason for not providing this support. Is there any way for me to handle Ipp8s datatype for above functions.

I have installed Intel IPP 2019.0.5.068 version.

thanks for submitting this request. currently there is no Ipp8s for these function.

For these two API, Ipp8u API can be used as workaround ( just input the input/output memory address as Ipp8u type), since the functions are just for data copy:

ippiCopy/ippiMirror

For ippiMinMax, can you convert into ipp16s type (by using ippiConvert) function, after computation, then convert it back to 8s type.

thanks,
