https://community.intel.com/t5/Intel-Integrated-Performance/YUV-to-RGB-convertion/m-p/974714#M20855 <DIV>I've noticed that the library has functions to convertyuv to rgb, but only to YUV444 and YUV422. I want to use this library to convert image data from IEEE1394 cameras. These camera output their data into YUV411,YUV422 and YUV444. Will YUV411 also be supported by the ipp library in the near feature?</DIV> Thu, 15 Jan 2004 18:50:27 GMT m_delorme 2004-01-15T18:50:27Z https://community.intel.com/t5/Intel-Integrated-Performance/YUV-to-RGB-convertion/m-p/974714#M20855 <DIV>I've noticed that the library has functions to convertyuv to rgb, but only to YUV444 and YUV422.

But for now we can't set the particular date when this functionality will be entered in the library.</DIV> <DIV></DIV> <DIV>Regards,</DIV> <DIV>Vladimir</DIV> Thu, 15 Jan 2004 22:34:42 GMT https://community.intel.com/t5/Intel-Integrated-Performance/YUV-to-RGB-convertion/m-p/974715#M20856 Intel_C_Intel 2004-01-15T22:34:42Z https://community.intel.com/t5/Intel-Integrated-Performance/YUV-to-RGB-convertion/m-p/974716#M20857 <DIV>One more question about the convertion. Is it internally done with floats or fixed point?I found some convertion code that clams its faster then the ipl library because it's uses fixed point calculations.</DIV> Thu, 15 Jan 2004 23:05:42 GMT https://community.intel.com/t5/Intel-Integrated-Performance/YUV-to-RGB-convertion/m-p/974716#M20857 m_delorme 2004-01-15T23:05:42Z https://community.intel.com/t5/Intel-Integrated-Performance/YUV-to-RGB-convertion/m-p/974717#M20858 Optimization techniques is depend on the algorithm and on the processor microarchitecture. So,in some caseswe may usefixed point implementation but in other caseswe may usefloat-point implementation. <DIV></DIV> Fri, 16 Jan 2004 16:03:34 GMT https://community.intel.com/t5/Intel-Integrated-Performance/YUV-to-RGB-convertion/m-p/974717#M20858 Intel_C_Intel 2004-01-16T16:03:34Z https://community.intel.com/t5/Intel-Integrated-Performance/YUV-to-RGB-convertion/m-p/974718#M20859 According to the IPP manual and to the IDC 1.3 specifications (firewire camera standard) the YUV422 is not the same in both cases.<BR /><BR />While in IPP we have<BR /> Y0 U0 Y1 V0 Y2 U1 Y3 V1 ...<BR />in firewire cameras we have<BR /> U0 Y0 V0 Y1 U2 Y2 V2 Y3 ...<BR /><BR />Why are they not the same?!<BR /><BR />Does any one have successfully use firewire cameras with IPP?

We do support one of them, you know, it is impossible to support all the features you can face in world.</P> <P>However,we plan to have some functionality for UYVY formats in future versions of IPP. So, I hope, we can provide you more possibilitiesin near future.</P> <P>Regards,<BR /> Vladimir</P> <DIV></DIV> Sat, 15 May 2004 01:41:28 GMT https://community.intel.com/t5/Intel-Integrated-Performance/YUV-to-RGB-convertion/m-p/974719#M20860 Intel_C_Intel 2004-05-15T01:41:28Z
