<div dir="ltr"><div><div><div><div>Hi, <br></div>yes it works better ... <br></div>I have also another problem: i have a 32-bit float image in input and the filter generates an image of 8-bit unsigned integer. I want to have 32-bit float in output.<br>
</div>Any way to do this?<br></div>Thanks !<br></div><div class="gmail_extra"><br><br><div class="gmail_quote">2013/4/26 Bradley Lowekamp <span dir="ltr"><<a href="mailto:blowekamp@mail.nih.gov" target="_blank">blowekamp@mail.nih.gov</a>></span><br>

<div><br></div><div><div>Self & <span style="white-space:pre-wrap"> </span>SetSeed (std::vector< unsigned int > idx)</div><div>Self & <span style="white-space:pre-wrap"> </span>SetSeedList (std::vector< std::vector< unsigned int > > t)</div>
</div><div><br></div><div>What you have as variable "seedList" is really just a single seed. In Java the types of the arguments for the above methods should be VectorUInt32, and VectorUIntList respectfully. You should be able to use the first one with your current variable.</div>
