A method for placing a human understandable item, such as a caption, text or a figurative element, in a digital image includes the steps of (a) digitally processing the digital image to recognize and identify an optimal location in the digital image for placing the item and (b) modifying the placement of the item in relation to human understandable image content so as to minimally obscure such human understandable image content in the digital image. The recognition and identification of an optimal location further includes the identification of an optimal open space region and then finding an optimal location for the item within the open space region. The placement of the item may be done so as to minimally obscure human understandable image content either in other locations of the optimal open space region, or in regions of the digital image adjoining the optimal open space region. Placement of the image may further be based on evaluating the proportion of image pixels in the item that occlude pixels outside of either the optimal location or the optimal region. Moreover, one or more attributes of the item, such as the color, size or shape of the item, may be modified in relation to the human understandable image content in the digital image to enhance the prominence of the item in the digital image. |
