Self-adaptive display method for image on display terminals with different sizes

Abstract

The invention discloses a self-adaptive display method for an image on display terminals with different sizes, comprising the following steps of: (1) constructing a visual attention model to obtain a final saliency map; (2) marking a most salient position: dividing the obtained final saliency map into blocks, marking the block with the maximum salient energy as the most salient position in the saliency map; and (3) self-adaption regulating: gradually expanding a display window towards x and y positive and negative coordinate axes according to the size and the proportion of a target display by taking the center of the marked maximum salient position as the original point of the coordinate axes. With the method, the easily occurred problem of loss of important attention regions of the image when the image is displayed on displays with different sizes is avoided, in addition, the distortion of the important regions of the image, i.e. the regions which an audience pay most attention to, is lowered to the minimum, thereby keeping a salient object in the display content accurate and complete.

Description

technical field [0001] The invention relates to an adaptive display method for images on display terminals of different sizes, and belongs to the technical field of image and multimedia signal processing. Background technique [0002] With the rapid development of network technology and multimedia technology, triple play has become an inevitable trend. The advancement of the integration of the three networks has made the use of multimedia resources more and more widely on small-screen devices such as mobile phones, handheld computers, and smart phones. Displaying images on these mobile terminals with small screen resolution, limited bandwidth, and processing capabilities has become a A salient issue. And with the further integration of "three networks" and the promotion of 3G communication networks, the diversity of terminal equipment has resulted. However, the production of an image is usually only for a certain type of display terminal. When the high-definition picture i...
