<FONT color=#000000>I´m trying to register two 2D cytology images with ITK.</FONT><BR>
<FONT color=#000000></FONT> <BR>
<FONT color=#000000>The images are really huge, about 4000x4000 pixels. </FONT><BR>
<FONT color=#000000></FONT> <BR>
<FONT color=#000000>I´m using an Affine Transform, MattesMutalInformationMetric, </FONT><FONT color=#800000 size=2><FONT color=#000000>LinearInterpolateImageFunction and <FONT color=#800000 size=2><FONT color=#000000>RegularStepGradientDescentOptimizer.</FONT></FONT></FONT></FONT><BR>

<FONT color=#800000 size=2><FONT color=#000000><FONT color=#800000 size=2><FONT color=#000000>The problem is that I can´t get good registration results. I´m trying to vary the values of the most important parameters of the transform, the optimizer and the metric, but I still get bad results.</FONT></FONT></FONT></FONT><BR>
