Hey everyones !
<br> <p>I have a problem with ImageRegistration : <br></p><p> I'm trying to register images (a Fixed image and a Moving one (same image but which I applied to a scaling,
translation and rotation transform). <br></p><p>I 've obtain excellent results when I
applied only a rotation and a scalling transformation.I based my code on ImageRegistration9.cxx and use a an AffinTransform based on MatesMultualInformation for the
metric, RegularStepGradientDescentOptimizer for the optimizer. <br> </p><p>Therefore as soon as I applied a translation Translation in X, Y, translation factors are
still very low ( near to 0) and results for other factors determination tion are worse. <br></p><p></p><p> </p>I supposed the problem come from Optimizer Scales and more precisely from adjustment of TranslationFactors towards rotation and scaling factor.<br>
I try recommandation "to use a factor proportional to the diagonal length of the image", Therefore I'm working on Satellite images with a resolution of 10 m by pixel.<br>Resultts using that estimation are worse. Have you got an idea of how I can solve my problem with translation factors determination ?<br>
