Quantitative quality measure for photorealistic three dimensional models
The demand for virtual photorealistic models has been recently increased especially in the field of documenting large archaeological sites. These models are commonly assessed qualitatively as no quantitative measure tool is available. In this work, a new approach is presented for a quantitative measure of models texture similarity. Deciding for the reference texture is crucial. Metrics that have been used ... Read more
