In other words, is the location of the upper left pixel of an image given by (0,0), (1,1) or (0.5,0.5)?<BR /><BR />Thanks Wed, 18 May 2005 23:34:08 GMT https://community.intel.com/t5/Intel-Integrated-Performance/ippi-Image-coordinate-system/m-p/990654#M22265 grose101 2005-05-18T23:34:08Z https://community.intel.com/t5/Intel-Integrated-Performance/ippi-Image-coordinate-system/m-p/990655#M22266 <DIV></DIV> <DIV>Hi,</DIV> <DIV></DIV> <DIV>in IPP pixel indicies are zero based and pixel location is from top-left corner.</DIV> <DIV></DIV> <DIV>I recommend you to read IPP Manual, volume 2, Image and Video Processing, Chapter 2 - Intel IPP Concepts for more details.</DIV> <DIV></DIV> <DIV>Regards,</DIV> <DIV> Vladimir</DIV><P>Message Edited by vdudnik on <SPAN class="date_text">05-24-2005</SPAN> <SPAN class="time_text">10:34 AM</SPAN></P> Wed, 25 May 2005 00:34:01 GMT https://community.intel.com/t5/Intel-Integrated-Performance/ippi-Image-coordinate-system/m-p/990655#M22266 Vladimir_Dudnik 2005-05-25T00:34:01Z
