topic How to Filter Two Channel Image in Intel® Integrated Performance Primitives https://community.intel.com/t5/Intel-Integrated-Performance/How-to-Filter-Two-Channel-Image/m-p/788063#M2184 Thanks Ying,<DIV>I have worked around this by converting to a planar image and doing a filter on planar channels. Seems to work ok.</DIV> Fri, 13 Jul 2012 21:18:00 GMT vetroxl 2012-07-13T21:18:00Z How to Filter Two Channel Image https://community.intel.com/t5/Intel-Integrated-Performance/How-to-Filter-Two-Channel-Image/m-p/788060#M2181 Hi,<DIV>I have a two channel image and I need to do a low pass filter on the image. I only see support for 1,3,4 channels. Should I use 16u_C1R mod and divide the steps by two? The layout of the image is 4:2:2.</DIV><DIV></DIV><DIV>Thanks.</DIV> Fri, 06 Jul 2012 11:37:11 GMT https://community.intel.com/t5/Intel-Integrated-Performance/How-to-Filter-Two-Channel-Image/m-p/788060#M2181 vetroxl 2012-07-06T11:37:11Z How to Filter Two Channel Image https://community.intel.com/t5/Intel-Integrated-Performance/How-to-Filter-Two-Channel-Image/m-p/788061#M2182 <DIV>You'd be wasting computation to use a C3R to just disregard the third channel. You've got the right idea.</DIV> Wed, 11 Jul 2012 14:13:46 GMT https://community.intel.com/t5/Intel-Integrated-Performance/How-to-Filter-Two-Channel-Image/m-p/788061#M2182 Ryan2 2012-07-11T14:13:46Z How to Filter Two Channel Image https://community.intel.com/t5/Intel-Integrated-Performance/How-to-Filter-Two-Channel-Image/m-p/788062#M2183 Hi Vetroxi, <BR /><BR />Just comments, <BR /><BR />If your image 4:2:2, 2channel is like YCrYCbYCrYCb.... <BR />there may two problems cause wrong result finally. <BR />1. two 8udata != 16u <BR />2.as low pass filter will use the neighbor pixer, you may mix Cr and Cb into computation. <BR /><BR />You may need check the ipp reference manual to choose some suitable functions or functions combination to do this. <BR /><BR />Best Regards,<BR />Ying Thu, 12 Jul 2012 02:46:27 GMT https://community.intel.com/t5/Intel-Integrated-Performance/How-to-Filter-Two-Channel-Image/m-p/788062#M2183 Ying_H_Intel 2012-07-12T02:46:27Z How to Filter Two Channel Image https://community.intel.com/t5/Intel-Integrated-Performance/How-to-Filter-Two-Channel-Image/m-p/788063#M2184 Thanks Ying,<DIV>I have worked around this by converting to a planar image and doing a filter on planar channels.
