Deep Quality Estimation: Creating Surrogate Models for Human Quality Ratings

Florian Kofler, Ivan Ezhov, Lucas Fidon +14

Human ratings are abstract representations of segmentation quality. To approximate human quality ratings on scarce expert data, we train surrogate quality estimation models. We eva…
