i have a problem with the classification wizard of ArcGIS Pro. Everytime i finish classification, artefacts were generated. Hopefully someone know a solution to remove these gray bars (image attached). I did a support vector machine classification with 12 classes included. The artefactbars always appear in the corners of the smallest geometry of my study site and are classified as the first class of my classificationscheme.
Maybe someone know how to handle this problem.
Thanks in advance
