discontinuity in registration #545

Closed mrrezaie closed 1 year ago

mrrezaie commented 1 year ago

Hi, I'm looking for a function to register the curves only horizontally. In Shift Registration example, the starting and ending points of the curves are also registered vertically. I tried Elastic registration example but it leads to discontinuities in my curves:

Any idea how to improve it? Any help is greatly appreciated. -Mohammadreza

Increasing the penalty parameter improved the curves.

Sorry for not answering before. Indeed, using the penalty parameter should penalize rough transformations and thus improve the curves.

@vnmabus Thank you so much for your response.
