In many cases this is only caused by the resampling and there is no reason to flag the respective tie point as an outlier.
A solution could be to disable the SSIM filtering for all tie points with shifts well in the subpixel range or to add some tolerance when comparing the pre- and post-coregistration SSIM. This way, the RANSAC filtering can still be turned on - otherwise it is also turned off when disabling SSIM filtering via the input parameters.Daniel SchefflerDaniel Schefflerhttps://git.gfz-potsdam.de/danschef/arosics/-/issues/54Allow to enable or disable the filtering techniques individually.2021-05-04T22:35:59+02:00Daniel SchefflerAllow to enable or disable the filtering techniques individually.Currectly, the user may set a filtering level between 1 and 3 but it is not possible to, e.g., disable SSIM filtering without disabling RANSAC.Currectly, the user may set a filtering level between 1 and 3 but it is not possible to, e.g., disable SSIM filtering without disabling RANSAC.Daniel SchefflerDaniel Schefflerhttps://git.gfz-potsdam.de/danschef/arosics/-/issues/69Local co-registration - automatically determine a meaningful grid resolution2021-11-20T02:06:18+01:00Daniel SchefflerLocal co-registration - automatically determine a meaningful grid resolutionThis would be quite useful, also see here: https://github.com/SMByC/Coregistration-Qgis-processing/issues/2#issuecomment-974558482This would be quite useful, also see here: https://github.com/SMByC/Coregistration-Qgis-processing/issues/2#issuecomment-974558482Daniel SchefflerDaniel Schefflerhttps://git.gfz-potsdam.de/danschef/arosics/-/issues/84Move random selection of 7000 tie points to image warping to allow feature tr...2023-08-10T12:28:06+02:00Daniel SchefflerMove random selection of 7000 tie points to image warping to allow feature tracking with more shift vectorsAs discussed in https://github.com/GFZ/arosics/issues/28, it might make sense to move the automatic sub-setting of the originally computed tie point list to the image warping instead of doing this directly when creating the GCP list. Cur...As discussed in https://github.com/GFZ/arosics/issues/28, it might make sense to move the automatic sub-setting of the originally computed tie point list to the image warping instead of doing this directly when creating the GCP list. Currently, at most 7000 tie points are auto-selected when creating the GCP list within the Tie_Point_Grid module. However, moving this to a later stage would enable to use AROSICS for feature tracking with more than 7000 tie points, where the correction of image displacements is not needed at all.Daniel SchefflerDaniel Scheffler
