<div dir="ltr">Hi I'm performing some Bspline registration and have looked on the list to find this information give regarding the number of samples.<div><br></div><div><pre style="color:rgb(0,0,0)"> The number of samples to take must be enough
for producing the same "appearance" of the joint histogram</pre><pre style="color:rgb(0,0,0)"><br></pre><pre style="color:rgb(0,0,0)">I have plotted the joint histogram but not sure what the same appearance means, how do I estimate the number of samples to use from the joint histogram?</pre>
<pre style="color:rgb(0,0,0)"><br></pre><pre style="color:rgb(0,0,0)">As an aside what drives the number of grid nodes to use, is it simply the detail in the image, the amount of motion?</pre><pre style="color:rgb(0,0,0)">
<br></pre><pre style="color:rgb(0,0,0)">Thanks for any help</pre><pre style="color:rgb(0,0,0)"><br></pre><pre style="color:rgb(0,0,0)">Emma</pre></div></div>
