ippiYCbCr420ToYCrCb420_8u_P2P3R and ippiYCbCr420_8u_P2P3R are the same

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.

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

Hi Inetsat,

Please find the below information regarding ippiYCbCr420ToYCrCb420_8u_P2P3R and ippiYCbCr420_8u_P2P3R.

For ippiYCbCr420ToYCrCb420_8u_P2P3R, its source is two-plane: Y + interleave Cb and Cr convert to three-plane: Y + Cr + Cb without interleave for Cb and Cr

For ippiYCbCr420_8u_P2P3R , its source is two-plane: Y + interleave Cb and Cr convert to three-plane: Y + Cb + Cr without interleave for Cb and Cr

The difference is the order in output, the First is Y, then Cr, and then  Cb, the second is Y, then Cb, and then Cr. The Cb and Cr order is different.

Best Regards,
