Image orientation detection using LBP-based features and logistic regression
Image orientation detection using LBP-based features and logistic regression
Many imaging applications require that images are correctly orientated with
respect to their content. In this work we present an algorithm for the automatic detection of
the image orientation that relies on the image content as described by Local Binary Patterns
(LBP). The detection is efficiently performed by exploiting logistic regression. The pro-posed algorithm has been extensively evaluated on more than 100,000 images taken from the
Scene UNderstanding (SUN) database. The results show that our algorithm outperformed
similar approaches in the state of the art, and its accuracy is comparable with that of human
observers in detecting the correct orientation of a wide range of image contents.
RESULTS
Classification accuracy on the first two levels of categorization. Note that some images belong to multiple categories and that, to simplify the analysis, they have been ignored, here.
