Hello, I have the following problem: when I open a geotiff image a negative spacing in provided in the y axis as the geographic value decreases with latitude. However, it seems that negative spacing is not welcome by ITK (at least I have read it in an Internet forum). For instance, in the example ImageRegistration1.cxx the RegularStepGradientDescentOptimizer does not work well when an input image has a negative spacing. Thus, I wonder if there is any smart way to avoid this problem. The solutions that have come up to me at first sight are:
- Check if the image has negative spacing ->put it positive (I have done it and at least the optimizer works well then) - Flip the image (I have not achieve yet to make the FlipImageFilter work) They seem rather rough approaches to me, so I wonder if there is any other smarter idea as I am a newbie with OTB and I do not know by far all of its capabilities (for instance, the FineRegistrationImageFilter does perform well with negative spacing).
