Beschreibung
Zusammenfassung:The invention discloses a sky detection algorithm based on context inference. The algorithm comprises establishment of a sky sample data set, a scene segmentation algorithm, extraction of super-pixel features, classifier training and establishment of a context inference model. A training classifier can be used to detect the sky area preliminarily; the CRF context inference model is established, so that the detection precision is further improved via context limitation, and a detection precision higher than a present algorithm is obtained; and a balance is made between the detection precision and the detection speed, and the practical requirements are met.
