Zhijie Zhao, Wu Qian, Huadong Sun, Xuesong Jin · Advanced science and technology letters · 2014
An effective method for sky region detection with color information and gradient is proposed. In the proposed algorithm, multi-border points in each column of image can be detected to complete complex sky region identification in image, and gradient and color information can be used to determine border point. The method proposed in this paper can deal with complex sky regions effectively compared with other sky detection methods, for example, sky regions are separated by buildings or flags. Experimental results have proven that the effectiveness of this method.
