Abstract
The paper presents a new method for the determination of an image orientation — the distinction between portrait- and landscape-oriented images. The algorithm can be applied to photographs taken outdoors. The approach is based on the use of a subpart of an image containing the sky. For determining the orientation the run of the standard deviation increment is analysed. It is obtained for the processed image and matched by means of correlation with the same characteristic of the sub-block of an image containing the sky.
