The role of orientation features in visual processing

Target recognition is an essential study path in computer vision since it helps recognize and localize image-specific target items. Scene context has been discovered to influence target recognition performance. What function does object and backdrop orientation play in the target recognition process? In the present study, consistent and inconsistent objects are shown in upright and inverted scenarios. In the experiments, whether in upright or inverted scenes, the response time for object recognition is shorter in consistent scenes than in inconsistent ones, and when the scenes are consistent and the object orientation is upright, there is a significant difference in the background orientation, with the response time for a upright background being significantly lower than that for an inverted one. Meanwhile, when the scenes are inconsistent and the background orientation is upright, objects with upright orientation have a considerably shorter reaction time than inverted objects. Taken together, these findings indicate that the orientation properties of the item and the background influence object recognition in the scene.
