Hello,
<div>
<div dir="ltr">
<div></div>
<div><br></div>
<div>I need a good resource for understanding splines very well. In fact, I studied different resources but something is not clear enough for me.</div>
<div><br></div>
<div>For example, when we use piecewise cubic splines, we find an equation for each curve segment corresponding the local segments of a shape, am I correct?</div>
<div>Then, how can we calculate a general function that we can use for any segment at the end? Or, do we transform each part separately, namely use each curve segment equation for a point within that local part? Are the weighted mean approach used for this problem? If yes, how can we calculate the weights for each part?</div>
<div><br></div>
<div>My mathematical background is not sufficient to comprehend all aspects, could you explain splines including TPS a bit? And/or could you recommend some good resources to understand splines from the point of image registration?</div>
<div><br></div>
<div>Thanks in advance.</div>
<div>Best regards,</div>
<div>Selma </div>
