Image Quality Assessment for Photo-consistency Evaluation on Planar Classification in Urban Scenes

In the context of semantic segmentation of urban scenes, the calibrated multi-views and the flatness assumption 
 
are commonly used to estimate a warped image based on the homography estimation. In order to classify 
 
planar and non-planar areas, we propose an evaluation protocol that compares several Image Quality Assessments 
 
(IQA) between a reference zone and its warped zone. We show that cosine angle distance-based 
 
measures are more efficient than euclidean distance-based for the planar/non-planar classification and that the 
 
Universal Quality Image (UQI) measure outperforms the other evaluated measures.
