METHOD OF AUTOMATIC PHOTOGRAPH FRAMING Russian patent published in 2008 - IPC G06K9/34 H04N1/38 G06T3/00 

FIELD: digital photography.

SUBSTANCE: automatic photograph framing method is suggested. In case of the album orientation of the image, the image horizontal line uniformity analysis is performed, whereas in case of the portrait orientation of the image, the image vertical line uniformity analysis is performed. The analysis is based on the line fragment clustering with the use of their texture attributes. Based on the analysis results, the number g(i) of different clusters including rectangular fragments covering the line, is determined. The g(i) number is used for estimating uniformity of the image line. Based on this estimation, the preliminary location of the image cutting frame is defined for the image. Then, the location of faces on the image is defined, and the position of the frame is corrected by finding the maximal y-coordinate y_t and the minimal y-coordinate y_b of the rectangles circumscribed around the defined faces with consecutive straightening of the image cutting frame with the centre of the vertical interval with its ends at the points y_t and y_b.

EFFECT: creating the modernized method of intellectual framing and cutting of digital images to be used in automatic devices of image processing and printing.
