Статистика

A lot of work has been done in the last 20 years, especially in the recent 5 years after the TLess and other textureless dataset were introduced.
We extracted edge features, feature combinations and RGB images enhanced with feature/feature combinations to create 15 datasets, each with a size of 340,000.
Model performance on dataset with HED edges performed comparatively better than other edge detectors like Canny or Prewitt.
