Hi,

 

ippiYCbCr420ToYCrCb420_8u_P2P3R and ippiYCbCr420_8u_P2P3R are the same function, even in the order of the parameters. They should share underlying code.

Hi,


Thanks for posting on Intel Communities. Please find the description of color conversion functionalities below.


YCbCr420ToYCrCb420

This function converts the 4:2:0 two-plane source image pSrc to the 4:2:0 three-plane image pDst. The first plane of the source image pSrcY contains luminance samples Y0, Y1, Y2, ..., the second plane pSrcCbCr contains interleaved chrominance samples Cb0, Cr0, Cb1, Cr1, .... The destination image pDst has the following order of pointers:Y-plane, Cr-plane, Cb-plane


YCbCr420

This function converts the 4:2:0 three-plane source image pSrc to the 4:2:0 two-plane image and vice versa. Two-plane image contains luminance samples Y0, Y1, Y2, .. in the first plane, and interleaved chrominance samples Cb0, Cr0, Cb1, Cr1,... in the second plane.


We would like to request you to elaborate your details a bit, so that it helps us in understanding the issue better.


Best Regards,

It's just that the functions do the same thing and waste space.
