Then I linked this program with two different ITKs (3.2 & 4.4) and tried running two executable on ~200 image pairs to find misregistration between each pair.<br><br>I was expecting same output from two ITKs(running system is same, Linux 32 in both case) but I am bit puzzled to see that there are misregistration differences between two ITK versions, Also these differences are not negligible they are of the order of 0.1m in a pixel of size 3m. Attached are misregistration results from two ITKs.<br>
<br>I guess somebody might have done similar comparison between different ITK versions, what is their opinion? Are these differences expected?<br></div>If differences between two ITKs are expected, then which one is better 3.2 or 4.4?<br>
</div>Thanks.<br></div><div>Any help or pointer in this respect is well appreciated.<br></div>BR<span class="HOEnZb"><font color="#888888"><br></font></span></div><span class="HOEnZb"><font color="#888888">Jagjeet<br></font></span></div>
