Method for adaptively displaying image by taking visual transfer mechanism as guide

Abstract

The invention discloses a method for adaptively displaying an image by taking a visual transfer mechanism as a guide, which comprises the following steps of: (1) constructing a visual attention model to obtain a final saliency map; (2) based on the saliency map, sequentially finding points with maximum saliency values from the saliency map according to a competitive mechanism; and (3) determining a final display strategy according to the size of a target saliency screen, a transfer sequence of attention focuses and distances among the attention focuses. By the method for adaptively displaying the image by taking the visual transfer mechanism as the guide and further regulating the accumulated energy of the saliency map after the display strategy is determined, an important reference is provided for the conventional adaptive method for performing cropping and seam carving only according to the accumulated energy, so that a user can fully understand image contents in an adaptive process, and less content loss and better user browsing experiences can be realized for the image with a plurality of salient regions.

Description

technical field [0001] The invention relates to an image adaptive display method guided by a visual transfer mechanism, and belongs to the technical field of image and multimedia signal processing. Background technique [0002] With the rapid development of Internet technology, multimedia resources such as images show an explosive growth trend. Especially the inevitable trend of telecommunications network, radio and television network and Internet three-network integration has further promoted the diversified development of information services and the rapid expansion of multimedia data. At present, due to the diversity of mobile devices such as mobile phones, PDAs, and smart phones, the use of multimedia content such as images on these mobile devices is becoming more and more extensive. However, for image information publishers, the release form of an image is only for a certain type of display device terminal. Therefore, this also poses a new challenge to the correspondin...

The content-based clipping method adjusts the content to be displayed according to the cumulative amount of visual saliency energy. However, this method may cause the loss of important areas if there are multiple scattered important areas in an image, such as Figure 5 In b, the chick is cut off, so the redisplayed image loses some important content

When the line clipping method is required to remove too many lines, it is easy to cause distortion of importan
