@adrtsc This looks good to me. I've fixed the import order & added a changelog entry. If the CI passes, I'll merge & release :) |

After running an old pipeline again on Fractal 2.0, Kelvin reported to me that his registration is worse. Back on Fractal 1.0, he used the apx_fractal_task_collection task for image registration, utilizing the chi2_shift algorithm for shift calculation. In Fractal 2.0, this has been integrated as an additional method in fractal-tasks-core. However, the original apx task additionally did a quantile rescaling, which helped when registering images that had very bright artifacts. This pull request adds a quantile rescaling step to the "Calculate Registration (image-based)" task to restore this behaviour.
