I create generator of augmented images. By contrast changer (gimp or from scratch using python), I can reach 100 score from bad image with 0-5 score, checking through arcoreimg.exe. Main question is why image, which has 5 score (pinned link), may has 100 score, when image has repetitive pattern?
"Best practices
Tips for selecting reference images
--Avoid images with repetitive features." from google
